GUEST: This is a photo album of my mother-in-law.

She worked at the Jasper Provincial Park, um, in Canada.

We figure about she was 16.

This is her here, and I don't know any of the other people.

Her dad w, was working at a lumber camp in Cold Lake, and I think it was just a summer job to get away from the lumber camps.

She never mentioned it, so we don't really know anything else.

APPRAISER: So, it's a nice family heirloom to have.

GUEST: Yeah.

APPRAISER: These pictures documenting her summer working at this camp.

But the reason we're talking... GUEST: Yeah.

APPRAISER: is that when we turn the page here, we suddenly see this.

So, what can you tell me about this?

GUEST: (stammers): Well... (laughs) APPRAISER: (laughing) GUEST: Uh, yeah, well, um, my husband was doing just that, looking at this after she passed away.

It was just in a box, and all of a sudden, it's, like, the "River of No Return."

And, and then we were, like, "That sounds like a movie."

(laughs) And so APPRAISER: Mm-hmm.

GUEST: Um, then they started looking some more, um, at the other pictures.

APPRAISER: So, if we continue through here, River of No Return, 1954, 20th Century Fox film that was filmed on location in Jasper National Park in Canada.

And most importantly, it's a film starring Marilyn Monroe.

(chuckles) GUEST: Yeah.

APPRAISER: She’s there with Robert Mitchum and Tommy Rettig.

Actually, Tommy Rettig is the child who played Mark Calder in the film, who was Robert Mitchum's son.

GUEST: Oh, uh-huh.

Yeah.

APPRAISER: Um, so that you have the core group of the key cast members here.

And what I really love about this is, not only did she get a nice, tight shot of them, Marilyn is giving face in this photo.

She is clearly turning it on.

The film came out, and it was an interesting kind of a departure for Marilyn.

She did start the film playing, like, the classic showgirl, saloon girl, but most of the film, she's in jeans.

GUEST: Yeah.

APPRAISER: And if we flip through here, we continue to see more Marilyn Monroe.

GUEST: Yeah.

This is her here.

This is my mother-in-law with APPRAISER: Rory GUEST: With Rory Calhoun.

APPRAISER: She obviously had access to the set.

We're not sure why.

APPRAISER: But she didn't just have access.

She actually was interacting with them in a very intimate way.

We see-- here she is cuddling up with Robert Mitchum.

GUEST: (laughing): Yeah, that's it.

That's my mother-in-law.

(laughs) APPRAISER: She looks pretty happy.

GUEST: Happy.

APPRAISER: I’m sure at 16, to be cuddling up with Robert Mitchum would've been quite a, quite a thing.

GUEST: (laughs) APPRAISER: And then of course, we also have Robert Mitchum's "Love and kisses, Bob Mitchum" signature.

GUEST: (laughing): Yeah.

APPRAISER: Um, and then, my favorite page of this whole book is where we land over here.

GUEST: Yeah.

APPRAISER: And we have the signature.

GUEST: Yeah.

APPRAISER: And we have a great shot of Marilyn right next to it.

And there's, overall, about 28 pictures of her and the, the area while she's on set.

And ten of them have Marilyn in them.

GUEST: Oh, really?

Okay, I didn't count that.

APPRAISER: So, did some counts.

GUEST: (laughing): Yeah.

Yeah.

APPRAISER: We had some people taking pictures on the set, like the person who worked for 20th Century Fox, whose job it was to document things going on in the scenes.

GUEST: Uh-huh.

APPRAISER: Those pictures would be very different from what we're seeing here.

These are very fun, candid, behind-the-scenes photos.

These have never been published.

GUEST: No.

APPRAISER: And what's astounding to me is that she never told anyone.

GUEST: She didn't.

APPRAISER: At auction, we do have records of other things similar to this that have sold.

And because they're unpublished and no one's ever seen these before, until today, we add up, and obviously, the Marilyns have the most value.

APPRAISER: So those would probably be sold almost individually.

That's how much people value hers.

GUEST: Okay.

APPRAISER: And those would be probably anywhere between $500 and $800 apiece.

GUEST: Oh, my goodness.

APPRAISER: Which, right there, counting up what we have here, is about $6,500.

GUEST: (chortles) (laughing): Oh, wow!

APPRAISER: And then you have this... GUEST: That was really loud-- sorry.

(both laugh) APPRAISER: Then we have this autograph.

This would bring about $3,000 at auction.

GUEST: Oh, my goodness, oh, wow.

APPRAISER: So we're up to $9,500.

GUEST: (chuckling): Oh, my goodness, okay.

APPRAISER: And then everything else would be about $500.

So we're about $10,000 that we would expect it to realize at auction.

GUEST: Oh, my goodness-- okay.

Wow.

I guess we have to up our insurance.

(laughs) Th... Okay.

I don't know what to say, honestly.

You're editing this out, right?

(laughs) I... Thank you.
