after taming the Monster, I began to be a bit singleminded about type collecting and now have over 200 types. I collect only from 1900-1939.
I basically have 3 foci
1) following the ACC and looking for one card for each
designation and sometimes an extra card or so if it's a Nagy or a Lionel Carter.
T's, E's, R's, W's, WG's, M's,and F's are my best work thus far with some attention to S's, B's, P's, PC's,C's, V's,D's, U's,H's.
(2) collecting T206 'era' packs,tins, pouches. (3) collecting Type 1 conlon,
thompson, van oeyen, burke, and brace with an eye for finding photos which were the bases for vintage cards,e.g. i have a conlon tannehill with its matching T206; a conlon Paskert with its matching T3; a burke Medwick with its matching s and s game card.
great fun.
I hope this helps.
best,
