Here is one. There are 13 different cards, with minor variations. This Kemler is also seen with an 1887 copyright. You can read more in Lipset's encyclopedia and/or the OJ book (The Photographic Baseball cards of Goodwin and Co.).
These are easy to find if you just want a common as a type. They are all portraits and like many OJ's it's more difficult to find them with sharp photos.
