Butterick Pattern 5496 contains yellow tranfers for floral designs and an alphabet. I also found an instruction sheet from Simplicity 8330 which goes over proper transfer as well as directions for basic embroidery stitches. Plus there is an floral embroidery transfer sheet for Vogue 1675.
Most of the tranfers have not been used and are ready for your vintage projects. Pattern envelope is old and has darkened. There is a small pen mark on the front of the envelope.
