Lot 12 D602 — Science and Industry — 1/19/83

This colorful stamp was released in Chicago, and on most of the covers, I used the official First Day of Issue hand cancel. Those covers are the #D601. On a smaller quantity, I opted for a special large hand cancel of "The Windy City" which is a cute and very appropriate pictorial. That cover is #D602, and it is the cover being offered in this lot. The hand painted cachet shows a scientist at a microscope and a booming factory scene. After obtaining the Chicago cancels, I flew back to New Jersey and drove to my unofficial city of Milltown where I obtained a clear round magenta cancel on a second Science and Industry stamp.
