In 1961, Karsten Solheim first produced the PING 69 putter, and a patent was received in October 1963. In his advertising, Karsten referred to the 69 series of putters as "Hot Dog" putters because of the shape of the head. Though Karsten preferred the name "69," which he described as "a pretty good golf score."  The shaft of the PING 69 putter is "fastened to sole for roll control," as a PING advertisement described. [And The Putter Went...PING (2017) by Jeffery B. Ellis].

"A vast majority of PING 69 putters use a single sight line. On a few of his earliest ones, Karsten tried a red or white paint filled alignment dot." [And The Putter Went...PING (2017) by Jeffery B. Ellis].

This Scottsdale PING 69 putter has the rare early white sight dot.
