Lambert Brothers, a New York City jeweler, produced their tethered sterling silver golf tees sometime around 1925.  Lambert was also making Walter Hagen's sterling silver putters by 1925. 

One of the tees in this set is marked "Lambert Bros" on its round length. The other tee is also a 1920s sterling silver tee. Unlike the Lambert Bros tee, this other tee is square down its length and marked "Sterling" inside the cup.   The former owner's initials are marked on the small plate in the middle of the sterling silver chain. A lovely display piece.
