Old Or New?

I know the picture's kind of blurry, but does anyone know if the stamp on the left is an advertising stamp for the 1912 Olympics? Or is it just part of a collection of stamps made later to show posters of past Olympic games? The one on the right is from the Delaware Tercentenary.





I know how everyone likes pic, I sure do, so here's a couple more of some Cinderellas I pulled out of a 2 pound box of Kiloware.











I know the last isn't really a Cinderella, but it's too cool looking not to include.

Thanks,
Jon
