I had a discussion on Facebook about Carter's watercolours and wondered if there was a collection of them. This post is the results of that discussion. Do you know of any more, or a published collection?
Carter started his working life in Egypt as an artist and only later became an archaeologist. His father was also an artist and Carter inherited his talent. Carter; having originally painted an image for the purposes of scientific recording, subsequently sold images like this to tourists.
The Griffiths Institute in Oxford has a big collection of his bird pictures.This is an example of one of them but there are lots more on the website. Howard Carter's watercolours of bird and animals
2) Highclere Castle
They have a fabulous picture he painted of the temple of Hatshepsut, this is a poor quality scan of the back of their guide book.
3) The Egypt Exploration SocietyEES have a number published on this link http://www.ees.ac.uk/userfiles/file/Images%20in%20Word.pdf .
4) From the excavation manuals of E. Neville's exploration of the Deir al Ba'hri.Here is one example.
