The above 3 images are by Robert Havell 1769-1832 an aquatint engraver of 5 Chandos Street, Covent Garden and were published on 1 Jul 1815 by John Wallis Jnr in Sidmouth and in London by J&E Wallis of 42 Skinner St and R Ackermann of Repository of Arts, Strand. They can be found in the George 3 Collection at the British Library. The original watercolour is by Hubert Cornish 1757-1823 an Exeter solicitor who painted it for his brother George who was Lord of the Manor at Salcombe Regis. It remained in the family until 1971 when it was acquired by the Sid Vale Association for permanent display in the Sidmouth Museum. A copy of the original is shown here whilst below is a composite image annotated to (incorrectly) show the location of Peak House (it is a little lower and to the left of the position indicated!). The publishing, artist, engraver and title information is shown in the 2nd print but applies to all 3 prints. Note the dedication to Emanuel Baruh Lousada, who is Emanuel #87 the founder of Peak House, developer of Sidmouth, and the first of the Peak House Lousadas. The dedication is part of the 2nd print, but is shown separately here for convenience.  
It reads 'To Emanuel Baruh Lousada Esquire, to whose active exertions and liberality of spirit the environs of Sidmouth are indebted for their principal charms, this panoramic view of that celebrated watering place taken from the beach immediately opposite the Marine Library and including an extent of country from Torbay to Bridport is most respectfully inscribed by his much obliged and obedient humble servant John Wallis Junior'. In the 2nd print, the Wallis name of the publisher appears on the prominent shopfront (an amusing substitute for the Marine Library the dedication suggests)!
