There was a thread some time ago about the "Toy Town Post Office" stamp. It's exact origin is still unknown but the general feel is that it was part of some type of toy.
Before the thread I had only seen the stamp on different sets of E-cards but I learned it can be found on tobacco cards as well.
To me it seems like it has no connection to any baseball set or card producer and in my opinion shouldn't be considered the same as a E94/E98 overprint as it just looks like one or more consumers "marked" their cards with the stamp.
If you're selling, it's a "feature".
If you're buying, it shold be considered "defacement".
