Lyle Sign Co. Street Markers » Circa 1970
Here are some of my favorite signs — the first (Pierce St. and 72nd Court W.) once stood in the front yard of my old house in Merrillville, Ind. This is a "Lyle Sign" manufactured by the Lyle Sign Company; each street name consists of two embossed plates mounted back-to-back and fastened with a bracket. Though they are still produced, these signs are becoming more rare because they do not conform to the standards described in the the Manual on Uniform Traffic Control Devices.

Chicago-Style E 81st St. » Circa 1950
A heavy-gauge steel yellow sign with attached mounting bracket (the bracket is literally part of the sign) was the style of all Chicago street-name signs from the mid-20th century until the 1970s, when white legends on green backs became the standard.
