From the early 1900's and to the late 40's Carmen was a great producer of expandable bracelets for adults or small children or babies. They were associated with Attleboro MFG Inc. They bracelets usually had a locket or heart as their trademark. This is very unusual the bracelet is very small for a small child or baby, I think it was hardly ever used. I is 6 inches not expanded but It did not expand a lot. From the High Plains of Kansas Expanding Carmen Bracelet!
