It's once again time for our collaboration with the always amusing What Is It? Blog. Can you guess what the pictured item is? Can you make up something interesting?

Place your guess in the comment section below. One guess per comment, please, though you can enter as many as you'd like. Post no URLs or weblinks, as doing so will forfeit your entry. Two winners: the first correct guess and the funniest (albeit ultimately wrong) guess will win T-shirt from the NeatoShop.

Please write your T-shirt selection alongside your guess. If you don't include a selection, you forfeit the prize, okay? May we suggest the Science T-Shirt, Funny T-Shirt and Artist-Designed T-Shirts?

For more clues, check out the What Is It? Blog. Good luck!

Update: Steve Pauk was the first one to know these are sniper's glasses; they were specifically made for the sharpshooters of the Civil War.  However, he did not select a t-shirt. The funniest answer came from Randall: "Eye training glasses, for G-men in the 30's. They helped develop that penetrating gaze that made the two-bit punks squirm like a toad in a vice while they were getting 'the treatment.'" Randall wins a t-shirt from the NeatoShop!
