Any Golfers? Found a rare (?) putter - Googling showed 1 other; from Bob Hope's estate sale!

I found this Bob Mark putter at my local thrift store yesterday. When I searched for Bob Mark putter only 1 came up - it was in a auction by Julien's Auction; who only does celebrities, etc auctions. It matched mine exactly - and it came from the estate of Bob Hope! (it sold for $288 - BOB MARK PUTTER (julienslive.com))

It has Bob Mark on the heel & MPC with a ruby(?) on the top. The side is a rainbow of colors!
There are no other examples that I can find - has anyone seen or heard of this putter before?
Thanks as always!

 

I don't know about your putter but my Brother in Law was (passed away a few years ago) president of Utah PGA. He worked at Tamaras country club in Ca where Bob Hope played. The starter they gave my husband a pair of Bob Hope's golfing pants. An ugly checkered pair that I use to wear for Halloween! I threw them out when we moved because I could not prove they belonged to Bob Hope. My Husband did caddy for him. He was not a very nice man behind the scenes. My guess is your putter will sell well even with out the Bob Hope connection. The colors scream 70's.

 

Thanks!
