A small portion of my collection consists of pins marked Made In W Germany. Whoever in West Germany was manufacturing these, they made a wide variety of designs, including flowers, leaves, butterflies, beetles, owls, and others. All are made from aluminum or a combination of aluminum and plastic. This pin is both materials (the flowers are plastic, the rest is aluminum).
The flowers are rather sloppily glued onto the leaf and the glue has yellowed a lot over the years.
