Oddly enough I was doing cartoons about computers back in the 70's. One of the first magazines to publish a computer cartoon I had created, was Personal Computing who were based in Boston. Many similar trade magazines devoted to technology and the soon-to-be technological explosion were launching and offering the public a subscription. Magazines such as Datamation, ComputorEdge (based in California), ComputerWorld, MacTech magazine Enterprise System Journal and a host of others were regular users of my work.
Over this period of time, I amassed a large volume of unsold cartoons and with the popularity of print-on-demand, it only made logical sense to come to Zazzle and offer my cartoons and humorous illustration on products.
