This field guide to North American birds features over 740 fair-feathered friends drawn to scale and sorted by species. To date, this is Pop Chart's best-selling print of all time.
An example "Perching Birds" categorization: the illustrated birds are organized into Family nesting boxes (above).
Below: illustration details.
With the success of this print, I re-worked the data to develop four mini prints focused on some of the most popular avian Families. These four minis (measuring 4"x6" each) can be hung separately or together as a set.
