Just wondering on the scarcity of the postcard and if anyone has seen one recently or has any information? I’ve been unable to find any. Also, I have not been able to find any sold. I’ve had it for about 25 years.
I did find an old thread on this forum
here from 2006 with some information but without photos.
From this link about postcard identification
http://www.playle.com/realphoto/ it looks like it’s from 1910-1930 era by the 2up 2down triangle stamp box.
