Jay sez, "Flickr set containing scans from a 1929 Johnson Smith catalog of 'surprising novelties, puzzles, tricks, jokegoods, useful articles, etc.' Catalog advertises real firearms, 'boy's handcuffs', Tear Gas in a fountain pen, Golden Shower bombs, and horribly racist masks."
(Thanks, Jay!)
Update: Mat sez, "1929 was a bit before my time. A while ago I scanned my cherished copy of the 1979 catalog and posted it on Flickr. Take a look — it's amazing how little some things change between issues."
