Pebble grain, a Haartz sample from 1923

Pebble grain is an old timer as top materials go, earliest forms of it going back into the days of rubberized top fabrics for horse buggies in the end of the 1800s. Variants of Pebble grain can be seen on top and coated upholstery fabrics from cars of the Brass Era (North America) and late Victorian Era (United Kingdom). Usage continued on folding top materials into the 1920s and on some top deck and roofcover materials into the 1930s. The Levant grain used on vinyl roofcover of General Motors cars from the late 1960s to about 1980 might have been derived from Pebble grain.
