I also found a typed (like: typewriter typed) daily newsletter from a cruise ship in Greece ("And the winner of The Most Beautiful Costume is POSSIDON - Mr. Moel BOUVET") folded up inside the atlas.
The internet tells me this particular boat --- Chandris Cruise Lines' Fiesta--was out of commission by the mid '70s, so this newsletter's older than me.
Also found this at the Botanica while looking for weird statuettes (of which there were an immense number, including some eminently Warhammerable grim reapers). Pretty intense for 1.95$.
Could come in handy though.
