Heisey's Glassware and Tenggren's history of glass

In the autumn of 1927 Gustaf Tenggren received a commission for an advertisement, depicting the Fenician's discovering the secret of glass-making. Situated in Newark, Ohio, Heisey's glassware was a well established producer of pressed household glass. From originally producing clear glass, in the mid 1920ies the company started to introduce brightly colored glass. Heisey's was the first glass company to use magazine advertising as an essential marketing tool.
In his income ledger Gustaf Tenggren has noted the steps through the delivery process quite detailed, making it possible to follow the complete order from the intermediating company, J Horace Lytle's Ad Agency in Dayton, Ohio.

December 1927: Original B-W watercolor for the ad "The Fenicians discovering glass". 

The first ad, in B-W only, was published in Saturday Evening Post in December 1927. It seems to have been very well received, as it were followed by four more in full color during 1928 and a final one in early 1929. Each of the following illustrations were executed as oil paintings and paid with $800 each, whereas the first B-W ad was $500.

January 1928: Marietta Beroviero reveals her father's craft secrets of
making colored glass to her lover, thus breaking the monopoly.
