I'm putting together a fictional league consisting of real-world teams/franchises, some from the past and some from today. I put a team in San Jose, and wanted the Bees to be the franchise, but couldn't find high quality logos, so I created them from some baseball cards I found online.
Not perfect, but better than anything I could dig up. Posting in case anyone can use them.
(If you want to read a long but fascinating story about the San Jose Bees,
this article is great.)
