Interesting blurb on the sale of Bowman to Topps, from Billboard Magazine Feb. 25th, 1956...."the Bowman Gum division of Connelly Containers...". Was Bowman possibly bought out before the sale to Topps? Connelly was apparently a printer - or paper manufacturer, haven't looked much into it - perhaps they did the printing towards the tail end of Bowman's existence?
Just throwing wrenches Dave, I'll post this on the non-sport side as well...
