Time for the Waltons. I almost reached season 7, the last season I will recheck. I have chosen these pics from disc 6 of season 6.
Pic 1 at 21 minutes (ep 19) showing Jim-Bob and Elizabeth sitting in the living room, before surprising their dad with the new telephone. Elizabeth’s bib are light blue, almost white bleached (the original blue color can be seen at close-ups). Also sitting on the ground outside, a bit earlier at 17 min.
In pic 2 she wore beige bibs, I think for the first time. A bit baggy, also rear view. Brief scene at 49 minutes (ep 20).
Pic 3 at 19 minutes again Jim-Bob and Elizabeth. Standing quite close to each other. Also walking, rear view. Elizabeth is still small in season 6 unlike in season 7.
Pic 4 Elizabeth at 1h20 in raw denim bibs like at 28 minutes.
Some few more scenes soon descibed at the season 6 entry.
