The current Fredericksburg building was built in 1953 using a similar design and signs. Carl's continues to make its frozen custard with the original Electro-Freeze ice cream machines which were purchased in 1947 for the original location. There are only about a dozen known frozen custard stands around the country that still use these vintage machines including: Hank's Frozen Custard in Conneaut Lake, PA; Glen's Homemade Custard in Springdale, PA; Putz's Creamy Whip in Cincinnati, OH; Carl's offers vanilla, chocolate and strawberry.

There was originally a neon skeleton sign of a howling dog installed in the window. The American flag sign was built in the 1940s. In 1955, the building was remodeled and the rooftop neon signs were installed. These non-animated signs remain and are lit at night. The dog sign is about six feet long. According to the sign shop that maintains Leon's signs, the dog sign would be the most difficult sign to replace because of the intricate neon bends. For more, see these websites: 1 and 2. [map]
