Outdoor Dimensional Display Co., Inc. was Bill Tracy’s first company, and was formed around 1960.

Messmore & Damon, Inc. was established in 1914 and was a manufacturer of many dark ride stunts and props in the 1960s, and supplied many fairs and other amusement venues with pieces to display. Although they tend to be best-known for their ‘Haunted House’ stunts, they also created animatronic animals and themed figures.

Unique Design, Inc. was formed in 1969 by Edward D. Hilbert and was based in Baltimore, Maryland.

One of the company's most well-known jobs was the re-theming of Kennywood's Old Mill in 1974.
