Signed & Dated William IV Portrait of a Rather Handsome Young Gentleman

The painting of this young gentleman is painted with a single colour watercolour on card and has written on one of the folds of his cape what looks like the name E S A Norman and the date 1834. I have tried to find an Artist during that period with that name but sadly have found no references. The painting I think is wonderful, catching what could be described as the 'arrogance of youth' as this young gentleman turns his head to look directly at us, his hand clutching the fur collar of his cape stopping it falling from his shoulders. His hair styled with those two incredible curls either side, frames that beautiful face with those strong eyebrows, large eyes and those pursed lips. There is a lovely immediacy to the portrait, one can almost imagine the fun that was had in the dressing up and the painting of this portrait. The painting is I think fine but there is one element that isn't so fine and that is his hand of which there is little sense of depth or detail, certainly not when compared with the rest of the painting. The portrait sits in I think its original frame of maple veneer with a gold painted slip and has aged beautifully with the portrait.
