MOW, I love other serious students of Ms Pedon. First, it's a different lounge chair. Note two things: 1) In the first picture the top 8 or 9 cross-strings on the back are of a sharply lighter color than the same area of the second picture. Second, note that in the second picture there is a screw in the left-hand (as we see it) upright tube of the back, between the 9th and 10th winding up from the bottom, but there is no such screw in the first picture.

The ground cover appears to be the same, but that is a common ground cover in California yards. My guess is that the shots were taken in different back yards and at different times, Jerry Stout met her when her part of the movie "Delinquent Schoolgirls" was being shot in May, 1973. He was the still photographer for the movie. At least three of the American Art Enterprises photographers who worked with Roberta also hired her for "speculative" private shoots, later submitting the pictures to various men's magazines. Jerry was one of them, along with John Kirk and Lance Kincaid. There may have been others; she was a very complaisant and marketable model.
