Unusual Early 70s Psychedelic Painted 7up Wooden Crate

Out of the Los Angeles area, this is an unusual dated Jan 1972 7up Wooden Crate with psychedelic paint. I have not found another in my internet search which leads me to (I think) two choices. The painting is good but not perfect. If this was a national campaign they would not have the rough painted edges on top & bottom. So perhaps this was authorized by the Los Angeles Bottling arm of 7up, for a regional if not urban promotion. OR - maybe this was just a California hippie's idea of a really cool record storage case. Not sure if I will ever find the answer... but filling it with period record albums sure works for me.
