Gashole. Co t-shirts are hand silk screened that are inspired by their obsession with the engine. Jay Thomas Mason started Gashole. Co as he has worked for a screen printer for others, and as a photographer and an artist, Jay wanted to put his other skills to work. He decided to start a line of his own designs printed in Jay’s So-Cal garage studio. The skirts are printed by hand in house, no auto press or computerized printers, pulling ink the old fashion way. Gashole’s shirts are printed on 100% cotton shirts and inspired by “anything fueled to go fast”. Gashole. Co’s designs are great for car and engine enthusiast’s, hot rodders, greasers, and anyone with a good sense of humor.
