I would say 1930's. Solid green and pink were very popular then, as were appliqued tulips. I would even venture to guess that the blocks were marketed by the Wonder Art label by Fixler Brothers of Chicago. They sold precut fabric shapes for one block at a time in a packet including the background fabric for 10 cents.
Your quilts are gorgeous and are in great condition! Lucky you.
