Blackberry is a middle period pattern introduced by Roseville Pottery in 1932. The pattern features bluish-black berries on green vines with yellow, orange, and green leaves on an irregularly molded green and brown background. Blackberry was originally marked with foil labels. Some examples have hand written shape numbers. Factory stock pages show 29 designs. The Roseville Blackberry pattern has been a long-time favorite among pottery collectors and that is reflected by the prices paid for the pattern.
