These are Workbasket designs for cards and wrapping paper. The only reason I think they are from 1941 is that there is a page from the Pennsylvania Farmer in the original envelope. I think they would be great for windows too. Click the pics for larger versions.
This little deer is so cute but the spots on the rump are a problem to cut into a stencil. I think freehanding them is best, even finger prints could work.

Nice tree. Love the bow detail.

This next one is my favorite. Those birds are great.
