I bought one of these for my dad for Christmas 15 years ago. Pete in Hilton Head contacted me to tell me I got ripped off. I was doubtful of his claim until he explained how the dirt was prinetd on and I looked closely. I really wanted the one I bought to be original.
The seller refunded my money and let me keep the calendar. It might still be hjanging on the wall in my dad's office. I'll look next time I'm over there.
Years ago there was a group of sellers all in the south selling these and other fake things like McCoy cookie jars and such. As far as I could tell one of the people in the south - it was small cluster of towns all in a 40-50 mile radius - was making the calendars. The pottery and stuff was Chinese imports sold by a wholesaler in the DC/Virginia area. The wholesaler had photos online of a warehouse full of fakes. Everything had peel off stickers saying "Made in China."
Scammers.
