This vintage set of Simplex drive-in movie speakers and glo-top junction box has been restored to a Sinclair Gasoline theme feature the Sinclair Dinosaur! This shorter desktop height stand makes it the perfect Bluetooth speaker to have on your desk, counter, or shelf, or workbench! It also has a built in MP3 player loaded with vintage drive-in movie and Sinclair gasoline advertisements! The set will run on AC or two hidden 9 volt batteries and has a remote control.
