Hi, found this on the beach in Delaware. Is this agate? Very hard and smooth. About the size of my thumb.

Fantastic thrift store find. This is a mechanical copy of a photograph by Rosenfeld mounted to masonite board. Has anyone ever seen this photo or know what the yachts name is? Thanks. It's a truly awesome image.

Thanks for any help. Found at a thrift store near the beach in Delaware. I can't really tell if it's a photo or a lithograph on board. The back is only brown board with a few marks on the upper corner with a tear.
