I have 3 pieces with same ID mark.  It appears to be "Bo" but could be something else.  I cant find anything about these pieces.  Now I am sorry I didnt find more out from the lady I bought them from.  She said they were from Germany. Thanks

Love the owl, I have Swedish dishware that is made by someone named BO AND USES THE INITIALS. May not be related but he is a famous designer could check into it/ dreamersgal
