Tim NewcombI have about eight of the photos you're describing (all 8 are on your checklist)-- no idea where I got them. I guess you could call them "1939 Cubs alternate picture-pack" -- probably distributed directly by Lotshaw rather than given out at the stadium.
The photos are definitely different from the 1939 Cubs Picture Packs.
The really neat thing about your find is the envelope, which would now allow someone to posit a checklist and name the set in a future edition of a catalog. SCD, are you on the case?
The other piece of info I can add is that Lotshaw as trainer appears in at least a couple of the earlier picture-packs-- 1931 for sure.
