Captain 20 promos and photos

The  Facebook page Captain 20 was my afterschool friend has some neat '70s photos of the Captain 20, a show on local D.C. TV station WDCA (Channel 20). Here are a couple images of a Washington Post ad and the Channel 20 Oath Card. There's also a photo of Captain 20 (who also played Count Gore De Vol, the station's horror host), the Banana Splits (characters of the the Krofft Saturday morning show of the 1970s) and kids on the Potomac.
