Blue Angels and Whales by Robert Gibbings
Pelican Special first edition. Number S16. Published 1938.
I believe this is the first Penguin book to include a coloured page.
Covers clean. Tiny chips at head and foot of spine with slightly rubbed hinges.
Pages clean but with darkened edges, especially on gravure plates. Tipped in page with coloured (blue and yellow) fish is foxed.
The photographs form part of the description.
