Beer - Made by the Schoenhofen Brewing Company of Chicago. Quite popular in it's day.
From the County Historical Society files:
"The Lighthouse Barbecue and Oil Station No. 10 was situated at the intersection of Sturdy Road and Lincolnway, where the south end of the roundabout is now [2017] located. The BBQ business opened on February 2, 1929, and was owned and operated by Alpheus Americus Williams. Williams had previously served as a professor of mathematics and vice president of Valparaiso University. The business did not exist long, likely due to the effects of the Great Depression. The lighthouse was functional and served as an aviation beacon. Note the misspelled "Dinning Room" signage on the left side of postcard."
