Thanks!David Shepherd (b. 1931) is a well-known British artist and conservationist, who maintains a wildlife foundation and sells his artworks to support it.Shepherd sells both original paintings and lithographed prints. Based on recent sales of comparable items, if your picture is in excellent condition and a print, signed by hand, its current retail (replacement or insurance) value is approximately GBP 80. If it is a print signed in the block (not in pencil, but printed on the paper), its retail value is approximately GBP 30. If it is an original painting on canvas, its current retail value is approximately GBP 300.If you were to sell it, you could expect to get approximately haf the retail amount.I hope this answer has been helpful to you, Helen.
