In the 1950s, before Castro turned Cuba into a Marxist paradise, the Tropicana was the hottest (upscale) nightclub in Havana.

If you got a souvenir photograph taken of yourself at the club, it came in a folder with the cover depicted above.  Back in Indiana, when you got home, you'd show it to all your friends, then put it in a drawer, then in a box stored in the attic, where it would be forgotten but slowly grow more magical with the years.

Eventually your grandchildren would throw it away, or dispose of it at a yard sale, in which case it might end up in the hands of a collector who would scan it and post the scan on the Internet, where it would become something to marvel at.
