Vintage Handmade Pottery Decorative Bowl

This decorative bowl is handmade from the 1960s or 1970s. The inside of the bowl has a raised design. It does have a maker's mark on the bottom but I have not been able to decipher it. Really beautiful vintage one of a kind piece. Note: There are a couple small bubbles that would have appeared in the initial firing of the piece. shown in pictures.
