Odd-shaped vase

This vase is interesting to me. It's 6.5" across and about 4.5" tall. Found in A thrift store in Portland, Oregon.

I know it's a long shot but any terms / direction would be appreciated.

There is perhaps an impressed mark on the bottom edge, but it's been obscured by glaze.

Thank you.

 

Looks more like a seed pot......

 

Modern studio pottery piece, I would think 1990s-present. Unfortunately I couldn’t help you on the mark, I do not know any US potters! It could be a local artist, or well know across the country - therein lies the mystery and the hunt we are all after!
