Royal Doulton "Celebrity collection" character jugs
This isn't the sort of thing we normally collect, but we got Groucho first and then it was just too tempting not to try to complete the series. But Clark Gable is missing because his jug was taken out of circulation almost immediately (his estate didn't like the likeness) -- so if any come up for sale they cost thousands. And apparently there's an early version of Groucho which has Chico and Harpo peeping round Groucho's cigar, but it was simplified as that version was too difficult to produce. That, too, is a real rarity.
They are Jimmy Durante, Louis Armstrong, Groucho Marx and Mae West.
