I think you did even narrow it down further, because I assumed the photos were taken in NY. The same four teams(not including Boston) I listed all went through Boston at that same time period, even shorter actually, May 11-20. Since Corcoran was released early enough to be announced in a May 21st newspaper, that basically means the Indy pictures were taken May 20th. Don't think any other day would've been feasible.

The White photo was just a guess based on the fact he was the 3B for the team and they only had eight players in the 1887 print run for the OJ set. Maybe the manager Bill Watkins played 3b for Detroit during this game I'm assuming. Wouldn't be far-fetched, he was a major league 3b in 1884 and played in the minors a few times after 1887
