No, not fans who drink beer. Art Rapp founded and Detroiters continued this group of connoisseurs of the labels on bheer bottles. The goal of the beerfan is to illustrate an APAzine with beer labels provided by his personal consumption during the period of publication; APAs require all copies of a magazine submitted to them to be identical, which adds a touch of business to the pleasure. Rapp has presented drawings of odd or local brand labels as a beerfannish activity.
