Less than a day left on these ebay auctions. Given the dearth of bids and watchers, it looks like not only will you be able to get them cheap, this’ll be your *only* chance to get them.

A while back I took a stab at printing cyanotype blueprints on canvas (the kind used by artists for painting on). After a rough start, I managed to get the process to work pretty well. It’s more complex and substantially more expensive than cyanotype printing on vellum paper, so I don’t know if I’ll make canvas blueprints available for regular sale like the paper versions. Still, I’ve put the first three successes on ebay if anyone is interested:

“Little Boy” atom bomb blueprint on canvas

“Fat Man” atom bomb blueprint on canvas

Dual Saturn V blueprint on canvas
