"I have come across a smaller version of what is described as a Turkey Red cabinet card. The card measures 3 1/2" by 2 1/2". It is a #2 Bergen.
Do you know if this could be a reprint?"
(The image above is a real T3 Bergen that was offered in a Mears auction...and sold for $44)
Yes, it's a reprint. T3s have been reprinted several times in what we now call "standard" size (which wasn't introduced until 1957). Authentic T3 cards are eight inches tall.
