<Tr> <Th> Designated VLR </Th> <Td> December 6, 2000 </Td> </Tr> <P> Carl's Ice Cream (also known as "Carl's Frozen Custard" or, most often, simply "Carl's") is a curbside ice cream stand located at 2200 Princess Anne Street, Fredericksburg, Virginia . Since 2005, the stand, with its Art Moderne architectural facade, has been listed on the National Register of Historic Places . </P> <P> Carl Sponseller founded Carl's Frozen Custard stand in 1947 . The original building was registered as a National Landmark and is an official register of Historic Places in 2005 . Since 1947, the 1940s era Electro Freeze machines have produced the frozen custard daily . Custard is different from ice cream because it contains eggs, and sells only three flavors, Vanilla, Chocolate, and Strawberry . When Carl retired he passed it to his brothers, Paul Sponseller and Herbert Sponseller . When they in turn retired it was passed to Ramona Sponseller (Settle), Daniel Sponseller, and Cristina Sponseller (McCann); keeping it in the family . The stand has what can only be called a devoted following, to the point that the line of customers often stretches around the building, even in bad weather . Carl's is seasonal, and closed each year from the Sunday before Thanksgiving until the Friday of Presidents Day Weekend . </P>
