Arthur Graham Reynolds CVO OBE FBA (10 January 1914 – 13 October 2013) was an English art historian who was Keeper of Paintings at the Victoria and Albert Museum. He was a leading expert on portrait miniatures and the art of John Constable, for whose works he wrote the catalogue raisonné.
A decent summary of artists who worked with watercolor from the 1700s to late 1900s and the cycle of watercolor being considered a sketching medium to fine art and back.
The book was exceptionally dry with simultaneously too much commentary and too many names/dates. The lack of colored images (although there were some) was disappointing. There was also no real analysis.
Not bad if looking for a summary of the medium + some artists to look up. Just make sure you have a decent amount of caffeine when you go in.
