Help to identify this piece

Hi im a.new member ....I have had this piece for 20yrs always loved it, ive been trying to find out who it's by has mark on base looks like TT any help would be very much appreciated thanks.

Alternatively it might be a JL mark. Not one I’ve come across before

Thank you Naomi will check it out have alsohad a message from someone stating it could be Toshiko Takaezu need to do some research,

Their mark was an incised II

I thought that also but have been told some of her earlier work wasn't it was glaze painted on will try and find out came across this which sold in auction 2013

They write TT on auction descriptions but the mark is always TT underlined so it looks II

I think Her earlier pieces were signed TT no underline that came later so I'm told? And some pieces unsigned I'm no expert yet but looking into it thanks for your help Naomi
