some years back, had the opportunity of interviewing 2 of PY Hahn's sons. They didn't really know much about the gun business. Had some great PY Hahn stories. One comment was, Do you know about the Christmas cards? Huh? Well, it turns out that every year PY Hahn would have a very high quality christmas card printed up and then the entire Hahn family would be used as cheap labor to assembly them (each issue was in the thousands, apparently)
So, for the serious Crosman Arms collector these Crosman Christmas cards are collectable. I have a couple of them and as I recall including this one now on Ebay.
Although more personal than business, since Crosman Arms Co. was printed on each card, PY would have written off the printing as a business expense.
