Green Butterfly POttery Ashtray - Hull?

One more request for the day... the lettering on the back of this makes me think Hull but can anyone confirm/deny this? It measures 10 1/2 inches across. I've seen a couple pieces out there similar to it but they did not identify the manufacturer. One piece that was numbered A-64 was billed as being made in 1964. Thoughts?

 

Lehner's shows lots of Hull marks and labels, but none that look even remotely like yours.

No I.d. Given, just for your reference on pricing. (No idea how reasonable that price is)

 

Thanks for checking. You reminded me I have a Kovel's book of marks but checking Hall and Hull (the two most common USA companies I could think of) didn't come up with anything.

Thanks, that was the one I was referring to above. Definitely the same manufacturer... whoever it may be

No, the mold numbers have nothing to do with the year they were made.

 

Yikes, looks like no one knows who dunnit!

 

I'm chasing the Haeger goose at the moment. According to this link they were one of the American potteries to use stilts for glazing and it seems like they use the copyright symbol on most of their markings.

 

Well looks like someone sold a yellow version of this on eBay a while back. Of course no manufacturer

Please don’t lable yours as a Hippie piece like they did.

 

Edit

 

Could be California Pottery

 

Agreed. "Maybe Psychedelic 60's Joint Disposal Container" would be better?
