It takes just a brooch back and a hot glue gun to convert kitschy childhood memorabilia into kitschy self-adornment. That said, I did actually buy these two. They never fail to attract nostalgic "oh I had those when I was a kid!" comments.

French brooch from Lea Stein, Paris. Production recommenced in the 1990s. Apparently:
"They are recognizable and desirable for their extraordinary colors, textures and patterns, derived from a painstaking hands-on lamination process, invented by Lea Stein and still used in contemporary jewelry. No two pieces are exactly alike; each is collectible, signed and referenced in various books."
