Pennsylvania TedWe don't have enough information at this point on this Mark/No-Mark phenomena.
We know that Demmitt (NY) does not exist with a Polar Bear and Sovereign 350 backs.
In fact he exists with only 4 different T-brands.
And, from what we have seen here (so far) with the Joe Doyle cards, we have to conclude
that there was an early press run of Polar Bears backs (on limited level of Subjects) in 1910
and then a later press run that year on a larger scale of Subjects.
