That Repton, with no real experience of practical horticulture, became an overnight success, is a tribute to his undeniable talent, but also to the unique way he presented his work. To help clients visualise his designs, Repton produced 'Red Books' (so called for their binding) with explanatory text and watercolours with a system of overlays to show 'before' and 'after' views. In this he differed from Capability Brown, who worked almost exclusively with plans and rarely illustrated or wrote about his work. Repton's overlays were soon copied by the Philadelphian Bernard M'Mahon in his 1806 "American Gardener's Calendar".
