The study sketch was almost certainly one of many that DGR was making
as part of his early training in draughtsmanship. Like so many of DGR's early school drawings, this one comes down to us
through DGR's early friend Alexander Munro (1825-1871), the artist and sculptor who associated with the PRB group and whom DGR proposed for the Cyclographic Society. Munro admired DGR and his work enormously. They probably met as students at the RA in 1848—an interesting fact since dozens of the early DGR drawings that Munro acquired date from much earlier. See
