Jensen’s collection features images of old Brentwood, Oakley and Knightsen, but she doesn’t have many Discovery Bay postcards. She’s been hunting for promotional postcards that were a part of the 1970s ad campaign to endorse the new waterfront community that nearly 15,000 residents now call home.
“There must have been postcards for promotion, yet no one seems to have one,” Jensen said. “This would be a 40-year-old card – too young to be extinct. Postcards of Discovery Bay are incredibly difficult to find. I searched, advertised and cried when I couldn’t find one ‘old’ promotional postcard of Discovery Bay advertising it from the 1970 to 1972.”
Jensen is offering a prize to anyone who can find a Discovery Bay postcard that hasn’t been sent or written on. This month she’s offering a Vaquero-level Friend of John Marsh membership to the John Marsh Historic Trust.
Jensen does own a Discovery Bay postcard, but not from the early days – yet the images lead to another history mystery. The postcard displays four scenes of the boater’s-paradise life in Discovery Bay, but the back of the card supplies no information regarding locations or identities.
Jensen wants to know things such as the name of the marina shown in the upper right corner and the owner of the house featured in the upper left corner. She’d also like to know the history of the sprinkler depicted in the lower right photo and where the lower left shot was taken.
Those with information on the postcard shown here, or in possession of a promotional postcard from the 1970s, should e-mail Jensen at email@example.com.
