This single 52-card deck showcases the impressive range of color patterns developed by ornithologist Robert Ridgway in 1886, originally used to standardize bird color descriptions. The design team at Roomytown in Bath, UK, created each card individually, using a selection of Ridgway's color patterns. Includes a standard 52-card deck plus two jokers. Packaged in a stylish, portable drawer box, it makes an ideal gift.
