Rich JacobsRyan: You suggested the cards were sold or given away by Peck & Snyder with a "blank back" so that the retailer could "print their own advertisement" and then also give them away to their retail customers. I may have misinterpreted this, but I read it as suggesting the retailer would purchase in bulk and have the printer put the retailer's information on the back.
I think it much more likely that they were sold by the printer only with the Peck & Snyder information, rather than printed with the retailer's information. If it were as I think you suggested, we ought to expect to see at least some cards with other than Peck & Snyder information on the back, but I'm not aware of any.
