Ducimus:
There are several pinup girl packs I believe. I remember seeing a few more mods pop up here and there to edit posters in radio room. This particular pack I posted around the time Aces of the Deep pack was released as a supermod (u can tell by the default sh3 dial textures in the screenshots). I liked their textures so much for the radio room....I added to them by replacing the posters with various pinup girls.

No, they are original pinups from the 1920's-40's by various artists. I googled alot of the images from collections on the net. You can also read about history of pinups and their artists here:
