Has anyone else noticed the subtle differences on the backs of the 1888 Goodwin Champions cards? One version has two lines at the bottom which read, "Goodwin & Co." with "New York." underneath, while the other includes a 3rd line which reads, "Geo S Harris & Sons, Lith Phila.". I found this interesting so I did some research (like 15 mins worth) and have only found two baseball players (Glasscock and Keefe) so far that I can confirm being found with both back variations.

Does anyone know why the difference and is this something that has been discussed before? I find it rather interesting and wonder if these two variations might have been printed in different locations or if one might be more rare than the other?

Here's a link that will allow you to quickly see what I'm talking about. It does not include two different examples of the Glasscock and Keefe but I was able to locate each on cardtarget.com.
