Curious Ephemera - Dead Geniuses Chess Set

This curious chess set pits (dead) mathematicians vs. (dead) physicists. John Ptak subitted this item in response to my recent call for ephemera that could be used in conjunction with DarkRoastedBlend's upcoming post on the World's Most Curious Ephemera.

When John Ptak, the mind behind Ptak Science Book blog, exhibited his books at the national/annual AMS APS meetings, he used this chess set for "some play," he says. "Ivariably the discussion was about why I chose certain people for certain positions," Ptak adds.  According to John, the pieces are all made of bits and junk and stuff like that, except for the faces, which were photos/engravings. 

It's not too late to submit your "curious" ephemera items to me for inclusion in the DarkRoastedBlend post. There's still a few days left before the deadline. Be sure to submit your item and grab some of the glory (and the link love traffic that's likely to result from the exposure).
