Holograms of Innovations & Patents
Calender 1997 with Holograms of Innovations
November and December
Crown Roll Leaf. Inc produced a very nice Calender 1997 with several important Patents & Innovations by using embossed holography. The Calender is in a perfect condition since it has never been exposed at any of our Hologram Exhibtions.
Here you can see two historical events in November 1814 and December 1877
