I see much more similarity to what I have in theses items.. Most noticeably plump with a red nose that lights up red & a big red nose that's a button (I think)

These are strikingly similar too

I'm in no way a WC Fields expert but the ones in your pix are skinny fellows not even plump faced (well all but maybe the clown looking one) & thus in no way resemble WC Fields. I have found several "village/town drunks" with light up red noses but they all have something in common, a street light & pole or a sign & pole of some sort.
Mine also has a cane another very well known WC Fields thing along with 4 other WC Fields traits "fat, red nose, top hat & hair color"! I guess if you consider a skinny drunk fellow with a top hat hanging on a light pole or sign the same as a plump guy with a top hat, a big red (light up) nose & holding a cane than they are indeed similar, I don't quite get the connection tho.
Three different people I know looked at this (at different times) & everyone of em said it was depicting someone famous, then they thought about it & all 3 of em said "oh I know it's supposed to be WC Fields". One of these people is an eBay seller who's been exclusively selling on eBay since 98 & sure that doesn't make their word gold but after a while in the business you start to know & recognize things. Japan made figures of "white" people that often made them look pigish or cartoonish or even scary. Their old Salt & Pepper shakers depicting black people often were quite raciest looking with stereotypical black people traits blown a little if not a lot outta proportion. I'm still not saying you're wrong just making a case for the conclusion I came to & sharing the opinions of others who have seen it in person.
Maybe this seller is reaching? But I don't think so I think they are right on spot with who Garfield is supposed to be.. Notice hes holding a cane, wearing a top hat & has a real big red nose + a written known way that WC Fields felt about dogs & kids.
A Japanese lighted red nose Santa.. notice how it looks strange, a little outta whack & just weird like most older Japanese made items depicting "white" people look. Its mostly the eyes here they made a white guy with slanty Asian eyes, oops. That freaky thing sure doesn't look like the Santa head made by USA companies from when I was young so maybe its really just a guy in a red hat, with a red nose, white beard & not really Santa at all? lol j/k
I guess this should qualify as being similar? Even tho no cane & wrong color hair + no top hat but he has a red light up nose.. & instead of Happy Daze it says Bar Open.
Another example showing how his nose was blown out of proportion + red & the reason things like the WC Fields red light nose battery tester was made later on..
