We have 3 Cows at the Beach Resin Brooches Vintage NOS.  They are in the original shipping clear bags.  I am selling them as sets.  In the first photo from left to right they measure as follows:  The cow with the floatie - 1 1/2" x 1".  The cow on the beach towel is about 1 3/8" x 1".  The cow under the beach umbrella is about 1 5/8" x 1 1/4".  They date to around the 1980's - some of the paint finishes are not quite perfect as shown in my photo's.  Cute set overall.
