Featured Anyone recognize this mark on pottery?

Hope everyone is doing well, it has been awhile. Probably a studio piece, but was hoping someone might have seen this before. Thanks for any input!

And here are the mugs that have the mark...

 

welcome back happy!

studio potters usually use intials as a mark, and sometimes they have to get clever if the same intials have been used before to differentiate

it looks like an opened postal letter.........but also see a B and backwards (yes a thing) C

 

Thanks for the welcome back, missed yall! Aghhh initials going to be hard if that is what that is.

 

Bumping in case someone hasn't seen this...

 

bumpity bump, Ya LIKE that

 

Huh. Hadn't seen them. They look like a cross between studio pottery and something mass made to look like studio pottery. But may be a case where you have to see them in the flesh to decide

 

I see a K

 

Julia K maybe? Google image suggestion but yet to find a mark to confirm.
