These blocks were printed as a set by William Pinch of the Rainbow Quilt Block Company in Cleveland, Ohio. He first produced these pre-stamped embroidery blocks in the 1930s, but they became very popular during and after WWII. I have researched the Rainbows for the American Quilt Study Group and you can find my paper in the 2009 Uncoverings journal. Pinch was a very prolific designer with over 1000 designs to his name, but he did not often label his work so identification becomes an issue. He did, however, produce over a million 9", 12" and 18" preprinted embroidery and applique blocks in a long career from 1925-1972. You have a wonderful quilt!

Sharon, thank you so much for taking the time to join QB to respond with such a wealth of information about these blocks.
It is indeed a treasure and I am so glad the OP rescued it and will do the research to ensure it is preserved or finished appropriately.
