This is a TRUE Vintage Giorgio Della Beffa perpetual calendar by Euroway from the 1970's. It is not a reproduction. It is stamped on one outer edge with Euroway Turin Italy. It is hard to read, but it is there. This version is very rare. It is small approx. 7"x7" and is made with thin Vacuuform plastic that is prone to cracking. It does have a corner crack and smaller cracking on 2 different sides. All 3 rings are cracked as well. They may be able to be repaired with UV glue. This table top version has thin cardboard attached to the back. It was designed originally to stand on your desk or table top or to be hung. The hanger is cardboard and is split so it would need to be fixed. The flip out part to use on the table has not been tested as I did not want to mess anything up. So the reality is the back would need to be futzed with to use in those 2 ways, unless you just wanted to prop it up or lay it flat. Also, the cardboard has water staining on it.
