Founded in 1959 by a graphic artist (Charles Hyatt), Hyatt's initially served the graphic arts and printing industry. Nowadays they continue to do so, but also offer a nice selection of supplies for all the fine arteests around town. They are located in Buffalo and Clarence, NY (and a few in PA). Hyatt's is a family-owned business that caters to "artists, architects, signmakers and designers of many disciplines."
They had a Rochester-area location in Henrietta near Office Depot. This closed May 18, 2014.
