From the recent Huggins & Scott auction:

It was a postcard featuring woodcuts of the 1893 Boston team. I did some research before bidding (I lost) and learned that privately issued postcards were not even legal in the U.S. until 1898. And it seems unlikely that the government issued any baseball postcards before then. This postcard was from Canada, which I assume had more relaxed laws about postcards back then. So what do you think -- could there be an earlier baseball postcard?
