It was an 18 hole teaser in the Olde Days of WGT, withdrawn before I joined.
Me thinks that it returned, modified, a year ago.
It's only 9 holes now in public play, but it's 2x 9 holes for CC CTTH tourneys. You can set up a full round there, and each shot is set up from a memorable shot of a famous golfer. The former teaser explained them with video clips.
The first in the current set-up is a shot by Hal Sutton who holed out at #1 from that position in 2000's US Open. The second, at #6, duplicates a TW shot to the green in two.
