Leather PostcardAround 100 years ago it was common to see depictions of Santa using a telephone, this 1907 postcard being a good example. This will be old news to the vintage postcard buffs out there, but I only recently discovered that some postcards used to be made of leather. Yep, leather postcards were fairly common for 3 or 4 years, but that came to an end in 1909 when the postal service prohibited their use. (supposedly because they jammed up the new sorting machinery) I’ve also included a photo of the back of the card.
