Card Identification Forum

Hi all - was hoping someone knew something about which set this is from. It’s Pepsin Gum from the late 1800s but I can’t find the set name and number. Any ideas?

Thank you!

So far all I have found is this thread. It's near the bottom.

Appears to be from E228/E-UNC

Here is a resource and some additional photos of cards from the set.

Another resource and starts of a checklists for each of the Harodil (E-UNC) and Faultless (E228) versions can be found here.

Those are great resources!  Thank you for that!

Thank you!
