|This card features both knitting and embroidery.|
I may be all wrong about this, but from my limited observations of greeting cards in recent decades, it seems that the 1970s -- as the United States approached and then observed its bicentennial, were a time to re-emphasize traditional handcrafts. A number of the cards I've seen from the 70s reflect this. Here are a couple of examples I've recently found.
The mitten card at the top of the post features a knitted mitten embellished with embroidery. To me it looks as if the mitten may have been sewed from a repurposed sweater. A veritable sampler of embroidery stitches adorn the mitten, from simple cross stitches and chain stitch on the cuff, to satin, chain, and straight stitches, plus French knots, on the hand part of the mitten. I like the design of poinsettias, holly, and snowflakes and am thinking it was no small challenge to stitch these on the cable-knitted mitten. Very unique and pretty.
