My colleague Gordon Henderson recently bought a packet of picture postcards at the Pasadena City College flea market. It appears that they were originally purchased at Kennedy's Card Shop in Los Angeles.
(Google Street View of the building that would have included 331 W. 5th St, LA 13)
The cards show scenes from across L.A.: An Easter sunrise service at the Hollywood Bowl, downtown's sparkling new Civic Center and Hollywood Boulevard.
Some also have writing on the back.
Scroll through the slideshow above. Can you help us date and translate the cards?
Also, let us know what's changed, what still remains, and any memories or thoughts of the time these postcards capture. The paper bag is a time capsule that you can help us unlock.
