Handmade Organically Shaped Vase in Soft Green Earth Tones

A primitive ceramic vase with an organic shape and striated patterns in soft green and blue earth tones.  The vase measures 4 1/4" across the base and stands 8 1/2" tall.  The rim opening is 2 1/4".  The bottom is signed by the maker, presumably a young person.  The condition is very good, with no chips or cracks.
