Regarding your question......
" Ted - T207s, I thought, were printed at ALC? "
It's my guess that these two 1912 sets, T207 & Canadian Tobacco set (C46), were produced by a different printer contracted out by ATC.
A printer that had barrels of Brown ink
So, it's my opinion, that the T207's were not produced by American Litho. Both of these sets do not fit the American Litho. style or format.
The T207 lacks the major Stars that were in the T206 & T205 sets. Furthermore, the T207 is made up of many obscure players not found in
those preceding sets. Factors such as these (and some others) have led me to this conclusion.
But. I'm sure others may differ.
