GUEST: They belonged to my great-grandmother.

Um, she worked for the Department of War and, uh, Department of Labor, and that she was a pack rat.

And, I mean, she just, she loved to collect things.

APPRAISER: How many of them are there?

GUEST: I'm... guessing about 50.

APPRAISER: I pulled out a couple of very specific and interesting pieces to talk to you about.

The ones on either end are a very famous figure in American World War II history.

It's Rosie the Riveter.

And one of the reasons why I love these posters so much... GUEST: Uh-huh.

APPRAISER: is that she is such a popular character... GUEST: Mm-hmm.

APPRAISER: ...and her image is so well-known, but you actually very seldomly see the posters.

GUEST: Uh-huh.

APPRAISER: Now, these are advertising the Women Ordinance Worker... GUEST: Okay.

APPRAISER: ...program where women were making shells in factories while the men were away.

And in fact, the one that's closest to you says, "'The girl he left behind' is still behind him."

Very, very popular and surprisingly, really rare in the world of World War II posters.

GUEST: Okay.

APPRAISER: Now, very differently is the poster that's in the middle here.

Now, this poster is by a very famous artist whose name is Ben Shahn, and his name appears on the poster.

And the story behind this poster is a page right out of your history class.

GUEST: Okay.

APPRAISER: In 1942, the Czechoslovakian resistance assassinated... GUEST: Mm-hmm.

APPRAISER: ...uh, Heydrich, who was one of the high commandants in the Nazi army, uh, in Czechoslovakia.

GUEST: Okay.

APPRAISER: And in retaliation, the Germans liquidated an entire village in Czechoslovakia.

They killed all of the men and deported all of the women and children to concentration camps.

GUEST: Okay.

APPRAISER: The town was called Lidice, and this poster is so somber and so grim, of a-- of a shackled man with his head in a bag up against a brick wall.

And it's meant to look sort of like a radio dispatch saying what happened.

Now, another image is this image up front, and it seems like a very simple poster.

It says, "give it your best."

It was meant to increase production in factories.

GUEST: Okay.

APPRAISER: The poster is not signed, but we know that it's by a very famous artist named Charles Coiner.

And this poster, because of its clear and obvious patriotism, is actually also very desirable on the market.

Finally, I want to show you something that I've never seen before.

And this is a group of posters for something called the O.P.A.

And the O.P.A.

is the Office of Price Administration... GUEST: Okay.

APPRAISER: ...which existed during the war specifically to keep people from profiting on, uh, gasoline, on rent.

And these are a very creative, very modern series.

They really-- they don't seem like they're from 1945.

Uh, they seem much more recent.

I've never, never seen them before.

And in fact, only just today when I went online to do some research, learned what the O.P.A.

was.

I'd never heard of the Office of Price Administration.

GUEST: Okay.

APPRAISER: So I think these are very exceptional.

If I had these posters at auction, I would appraise them in the following way.

The two posters of Rosie the Riveter, uh, each by Adolph Treidler, by the way, a very famous artist.

GUEST: Right.

APPRAISER: I would estimate each one at $1,500 to $2,000.

Okay.

The Ben Shahn poster, I would estimate at $800 to $1,200.

GUEST: Okay.

APPRAISER: The Charles Coiner-- "Give it your best," the American flag-- I would estimate at $700 to $1,000.

GUEST: Okay.

APPRAISER: And all of these posters for the Office of Price Administration, as a group, I would estimate this group alone at $1,500 to $2,000.

GUEST: Oh, cool.

Okay.

APPRAISER: So, together now, we're looking at between $6,000 and $8,200.

And that's just for the ones we're looking at, not for the other ones that are in the pile.

GUEST: Okay.

Great.

APPRAISER: How does that sound for a piece of history?

GUEST: That sounds great.

I had no idea.
