PARCO Faucet Washers! Various sizes, all BEVELED and PACKED IN THE U.S.A. BY UNION LABOR.
I'm pretty sure the actual age order, oldest to youngest, is peacock blue with price, peacock blue with price covered over by a sticker at the factory (the sticker is under the plastic), then the orange pair with the tree cut off because they reversed the size and price sticker position layout.
The design time is certainly late 1950s to early 1960s - the diamond windows in that ranch house with the open roof above the porch screams 1962 to me, but could well be earlier seeing as it's California. (The double-width garage, same notation.)
I like the little caricatures too.
PARCO made it until 2016, when they did not in fact go out of business but got bought out! So they're now a division of a large company. At some point they moved from Bell, California to Ontario, California, but it's not exactly a big move, it's all part of the massive LA metroplex. I don't know where they were in Bell, but there's a big industrial area with some old (and disused) railroad tracks going through it, though, so I imagine that's where. There are a couple of industrial buildings on Randolph that look just about old enough. And I think there were more, but they got torn down and replaced with newer in the last couple of decades.
Anyway. I like the house, I like the PACKED BY UNION LABOUR. Gods only know how badly those faucet washers have degraded, though. That's some nasty plastic. xD
