I’m interested in boxes from 20s to 1980s and the respective sleeves used in them. I have not reviewed them! Could you point me in the right direction? I like also the sleuthing and historical factor involved. Example when the ole lady became queen and the writing that changed on the boxes.Boxes I can sometimes dig up, cases and sleeves generally not. What era are you looking for?
Have you reviewed the fairly complete runs of catalogs floating around? That might be a decent chronological source.
