Since the subject of 'old books' attracted some interest on another thread, I thought I'd share some photos of a prized possession--a First Edition of Innes's Exotic Aquarium Fishes, 1935, signed by the author. He inscribed the book to Louis Mowbray, former director of the Bermuda Aquarium and later holding the same position at Boston Aquarium and New York Aquarium. He has a wikipedia page. The edition is exceptional for several reasons including a supplement that was belatedly added a day before the galleys went to the binder. Said supplement documented the very first successful spawning of Discus in 1935. I purchased this for $30 many years ago. One of the smartest things I did when I was young.
