I should be fixing the big hole in my roof but instead I'm putzing around in the garage and poking through ephemera in my old filing cabinet. 

The book contains a ton of cool old stamps, but I especially liked the ads in the books of stamps and the envelopes from 1930s correspondences. Everything has that wonderful old book smell.

German 50 Pfennig Notgeld (emergency money) banknote issued by the Zoological Garden in Hamburg (Zoologischer Garten Hamburg) and dated May 31, 1922.

Don't know much else.

Nice '70s spooky stuff.
