Most of these are the same posters that come in with the Aqualog "Specials" series of books. They come folded and are designed so that they may be displayed as one poster on a wall or cut into sections and put into a notebook. Several posters are available covering topics such as Malawi Cichlids, Loricariidae, Discus, Goldfish and more. Posters have between 48 and 64 color photos each.
