VINTAGE "BINKYS PERFECT TEETHER" 1940's 
MADE IN U.S.A.

Dimensions ~ 3 3/4" Length x 2 1/8" Width

This vintage baby teether is quite firm.  I'm presuming back in the 1940's that it might have been softer and just hardened up over the years?  It is a tan color and has the raised lettering around the larger circle, "Binkys Perfect Teether".  Around the smaller circle which a strlng could be strung through are the words "Made in U.S.A."  The Binkys Baby Products Company was located in New York.  I couldn't find any further information on the company.  It is in overall very good condition consistent with its age.  Your grandmother's (or great-grandmother's) teething ring.  :)
