I have a Wills' Cigarrettes card of Edu Meyer depicting a bud and open flower with foliage. The bud is pink/orange color and somewhat pointed. the flower looks like it has about 20-24 petals, pink petals with a golden reverse. The stems don't look particularly prickly. It would be nice to discover this plant again.
