1889 Old Judge question
 

A Mills of Milwaukee- WA just sold on eBay with the caption showing the league designation as well as the team. In my limited experience, that struck me as rather unusual. How rare is that in context of the WA cards from 1889?

They are not common, but I've seen a few examples over the years from different players/managers/umpire, so they are out there. They do tend to stand out when you see them. I noticed it right away on the Mills card as well

for reference ...
