Thanks guys for the compliments.
Given that these DRUM's are so scarce, the intent of this thread is to provide a guide to inform you if your favorite T206 exists (or can be found) with a DRUM back.
Now, I would really appreciate it if some one on this forum can find me a blue portrait Hal Chase with a DRUM back.....so, I can complete my "Quintuplicate" sub-set.
I've been searching for a Chase / DRUM since 1984, when I acquired my first T206 DRUM card (Moeller).
