The Clarke-T, made from bakelite, is designed with a track for the "cup", so the golfer could align the tee in the direction of the ball and the track would help the ball fly straight.  "Clarke-'T" is marked on the top of the tee.Irwin Valenta in his book The Singular History of the Golf Tee calls this the Clark Track Tee.  Circa 1928

The Tee Cup, marked "Patent Pend, Fabricord, New Haven, Conn" on the base and "Tee cup" on the top of the short extension, is shown in Irwin Valenta's book and described as made from bakelite.

The Tri-pod Tee, as the auctioneer calls it, is not marked and appears to be made from bakelite or some other hard resin.

All three of these tees are in great shape and a date to the 1920s-1930s.
