Vintage hot iron transfers for pillow cases, guest towels and linens. The back cover provides stamping instructions, suggested fabrics and material for embroidery including color schemes. There is no date on the envelope or pattern, but I believe this item is from the late 1930s.
The envelope contains a single factory folded sheet of transfers. The transfers are printed on a heavy paper, not tissue. The patterns are still slightly raised, indicating it has never been used. There is a single tear on the paper, where it has been folded. That should not get in the way of making the piece.
