Ah yes, the boys from "First Date" 1944, Merrill. Page 118 in Tomart's PRice Guide to Saalfield and Merrill Paper dolls. I've got the complete set cut-out. I'd have loved to also have the folder but alas it was long gone.
Tattered and Lost beat me to it- I don't have the set, but I do have scans of an incomplete cut First Date, and those boys are definiitely part of that book.
