Christmas Postcards,Vintage unsent, FEATURE DOGS

I have Postcards featuring cats, but these are the only cards of this genre which I have that feature dogs, Gold background. One in nice shape and one not. Bought at different times, I wonder about more of these because the backs say "Christmas Dog Series" They are deeply embossed CB brand vintage cards; I'd say 1908-14. Too bad one was was in poor shape but I wanted it to add to the other I had. I do keep an eye out for more of them, if available. See the backs as well, Regarding the the card at left, some of the print on the back, shows thru the gold on the front, and you can read it mirror vision of the front. That I have never seen before on a card. (Made In USA)
