Tobacco Jar identification

Here is another of my unidentified pieces, this one passed down from my Grandparents.

The jar was part of a pair my Grandmother called Sam & Helen but at some time long ago the other one got broken. there are some things on the base, letters BB are stamped but the others hand cut before firing, in the circle looks like DrP

 

Try Bernard Bloch.

 

I think that's DEP in the circle, which likely stands for depose and indicates the piece to be French.

 

Dep could indicate French but not necessarily. Here is what Chris says.

If it's Bloch, which seems probable, then it's Czechoslovakian, and that mark in the circle means something un-French.

 

1/2 hour? Where did that 1/2 hour go?
