Adam - great postcard, and very nice contemporary piece for Weiss (and Bender).
As you mentioned, there aren't many contemporary cards picturing Weiss. There is a Cabinet with the same image as your postcard (cropped a little differently), but the image I have is super low quality.
Here's my site showing all of George's "rookie" cards/photos. The earliest card picturing Weiss is a c1914 New Haven Team postcard; and his earliest known "individual" item is a 1919 Roger Sherman Studio Photo.
