The famed H.M.S. Associates product development and design studio was here. The company existed from the late 1940s to 1994. There is a lot about it on the Web, including at https://www.ebay.com/itm/1963-Aurora-Thunderjet-Buick-Riviera-Original-Blueprint-Prototype-Photos-HMS-/182393907458 and http://www.daveshobby.net/aurora-amx-3-up-prototype.html (speaks of legendary sculptor Bill Lemon). It designed many toys and other products, including Hess Trucks, Aurora Thunderjet HO slot cars, Aurora superhero and monster models, refrigerator air fresheners, Zippo lighters, the spiny stem for artificial flowers, and buildings for model train layouts (see the Tyco HO lighted building - Church # 941 - modeled after a real church, also on www.roadsidehistoricalmarkers.com).
