L.A. Journal (via Curbed L.A.) has an excellent pictorial history of a public art project at the northern tip of Elysian Valley. One caveat, however: Viewers from outside the neighborhood should know that residents prefer the designation "Elysian Valley" to "Frogtown". The latter, though it once referred to the frogs that would pile up on front lawns when the L.A. River overflowed its banks, has more recently become the name of a gang that has been responsible for various crimes in the area. Enjoy!
