Vintage Unknown Finds

This etsy seller has these four owl images from 1972 for sale made by Morris Manufacturing Co. of Garland, Texas, a subsidiary of American Arts & Crafts Corp. The images feature four seasons and in each season the owl is busy doing the following tasks - raking leaves in the fall, making a snowman in winter, picking flowers in spring and fishing in the lily pads in summer!  The seller is not sure if these are transfers. Do you know what are these?
