Swallow Bird Brooch Marcel Boucher by Marcel Boucher
Once I've researched a little, I've come to the conclusion that this unsigned and very rare Swallow brooch was made ​​by Marcel Boucher under the patent number of 129842, granted on Oct.7, 1941 . The metal has a matte silver color as "pot metal" . It is a very old piece and therefore not absolutely perfect, but it's pretty close.
