Love this piece (just not sure who created it and I cannot make out markings on bottom?) Any ideas?

Hi, I found this vase/amphora @ thrift store and just loved it. When I got home I looked at it more carefully and say what look like markings on the bottom (to me it looks a picture of a person with a net trying to catch a butterfly.) I have spent many hours researching and trying to find something similiar, but no luck. I have no idea, please help. Thank you.
