For the WSC60s 906.
Probably the only (if not, one of very few) pink Porsche 906's from the 60's.
I've tried to dig up some information about the driver, Cliff Phillips, but came up almost empty handed. The folks at RSC have a decent racing record of him and showcased his love for Porsches. He started racing in a Porsche 356 in 1958, then moved to a 550 in 1959, 718 in 1960 - taking a brief pause with Porsche's in a Corvette (which was a DNF on its sole race) - then going back to Porsches after a 6 year hiatus: this pink 906.
This livery represents the car at the Full International Can-Am Road America at Road America 1967, where he finished 4th in the Revson Trophy support race.
