Here's a real photo postcard, black and white, that depicts a Model T Ford, at least I think it's a Model T Ford. Inside, a group of passengers, perhaps a family. The card is interesting in that the back tire has chains on it - there's no snow in sight but I think the card has been riding muddy roads. In looking at the photo with a loupe, the car holds two couples and on the front window is a felt pennant that reads K-R-I-T.
The postcard is postally unused and in fair condition with a touch of discoloration to the paper. The photo is light but not overly so.
The card measures 5-1/4" x 3-1/2" approx - just average postcard sized light cardstock.
