T224/T229 need clarification

[G1911]

The Pet and Kopec sets were split into two by Burdick, before the 'error' here was corrected and the sets united into one.

They were almost certainly printed by the same printer who did T212 Obak. It is probably a late 1911 or 1912 issue, based on the events mentioned on card reverses.

A significant number of cards seem to have purple stamps on the back.

I think there are 40 cards with no short prints (some seem less available because they are more popular and sitting in collections). It appears all cards have both Pet and Kopec backs, but I have not confirmed them all or kept scans. Hopefully the formatting is preserved, but here is what I have as the checklist.
