Here's an auction site that had a bunch of this type of thing (but not that flapper). Good because it gives other companies that used that format: https://www.auctionbymayo.com/searc...pleted/all-categories/IA?terms=&dist=&postal= If you can find the printer's name on the piece, that's obviously another trail to follow.
Here she is. Selz Shoes. And 1918. A tad earlier than I thought. https://bid.wearsauctioneering.com/.../lot/5671010?utm_source=www.auctionbymayo.com Debora
You can be pretty sure that whoever printed these had sales people out there promoting them as calendar material, or in any other application that might sell, to whoever might be interested in buying them. It's not impossible that a given image could have been used by several different companies. Depends on the terms of the sale.
Cleaning them up,and the colors are so much brighter than under that filthy glass ! This is the back of the lady in black,says only "b9130 gift" in pencil. On the front bottom you can see the top of something trimmed off. I wonder if the husband worked for Pabst ?
I have gone through some of the things I have recently inherited and added information like "wedding gift" so that my grandkids will know. I agree that they were odd wedding gifts unless there was some personal connection.
My mom said she got the oddest things for their wedding,some obviously hand me downs. But they were newlyweds and had nothing,so she appreciated it all. Maybe Leona just loved them !
Think this is helpful to see how calendars would originally have appeared before they were cropped. Debora
