Case Island is located in Genesee County, Michigan, south of Flint. At the time that this postcard was printed, the island was located in Long Lake, but the lake was later renamed Lake Fenton. Per authors Donna and Kenneth Seger, the name change was the result of a petition started by one of the long-time island residents. At this time there were over a hundred other Michigan lakes called Long Lake. A Wiki entry indicates that the name change officially took place in 1932 – a decision made by the United States Board on Geographic Names. (The BGN is a federal agency of the Department of the Interior.)

Since this is a divided back card printed in Germany, the estimated date would be from about 1907 – 1914. Easy to miss but on the front “in the lake” at the bottom right, is printed what appears to read as “A67977.” Since the postcard number is already identified with the publisher info, then one assumes the number on the front may be the series number (unless vice versa.)

Divided back, unused postcard. Printed in Germany. Publisher:  Backenstose Bookstore, Pontiac, Michigan. No. 31436. Series? A67977.
