Thimbles, thimbles, and more thimbles

This lot contains 17 thimbles.   Six of them are plastic advertising thimbles:  four of them are advertising companies in the San Francisco region: Holstein's Pastry Shop (2), Taylor's Dairy,  and Exhibit Furniture Company.   The dark red plastic thimble advertises Greer Realty, and one of the white plastic thimbles salutes Nixon for U. S. Senator.   

The metal thimbles range from aluminum (1), to brass to regular thimbles.   One has a petitpoint top and a "gold" finish;  one is marked The Prudential Life Insurance; one  has a blue rim and is marked Vote for E.E. Roberts for Senate.    

The key chain pendant opens to reveal a thimble, a needle holder and small thread holders.   While I can't be sure of age I think this is a newer piece.
