This is for a lot of 23 tin litho bird pins that were produced in JAPAN.  The colors are bright and i believe the styling is representative of the late 1960's.  They are a fun lot and represent birds as different characters...a little reminiscent of the old classic "Birdlife in Wingtown".  I wonder if these pins were party favors, store promotions, awards, carnival prizes?  There are 2 cowboy birds, both a different design. There are 2 "maestro" birds; 3 beach chicks, 4 camera/smile birds, 3 cigar/glasses birds, 2 gentleman, 4 pink bows, and 3 Sgt. Pepper.  I think that the condition is above average considering their age and i believe that the photos accurately depict this.  Estate sale find.
