Bart, I waited for somebody else to comment, before I chimed in.
When I was a high school student ( dinosaurs did roam the earth ), these were collector's items.
There was a protocol to follow whenever there was was one calendar available for passing around.
Costa, one of my friends, would be the one that somehow managed to get hold of one. He was the ' chosen ' one. Secretly we believed he belonged to the Cosa Nostra, hence his luck with all things Italian!!
Your post brought me back to those lovely lovely days in England, where 12 photos started fistfights amongst the best of friends.
Thank you.
