This smallish perched owl diecut was made by Hallmark in the later 1940s. It was sold as one diecut of a boxed set of diecuts. (Hallmark didn't seem to have a standardized set of diecuts sold in their larger box, but seemed to have a varying assortment they sold over a handful of Halloween seasons.) You can see what the box looks like if you turn to page 164 of my new third edition. (Hallmark sold place cards in a smaller, otherwise identical box.)
