This nativity scene was part of the civic Christmas decor in Huntington Beach in 1950. You can see a bit of the Pavilion (a.k.a. the Pav-a-lon) behind the palm fronds. Duke's restaurant now stands at this location.
This scene was part of the "Forty Miles of Christmas Smiles" decorating contest, which was sponsored each year by the Orange County Coast Association. If I were judging, I think I'd have to mark my hometown down a couple points for that Joseph figure. He looks suspiciously like a female department store manikin. (It also reminds me of that scene in Life of Brian with all the women with fake beards taking part in a stoning.)
