Studio Art Slab Built Pottery Vase Petroglyphs Signed SLS

Studio Art Slab Built Petroglyphs Pottery Vase Signed SLS? I think it's marked on side SLS. Not sure what is on the front of it some type of petroglyphs? Marked with X in marker on bottom.

No chips or nicks in good shape. If anyone has any ideas on maker I would appreciate a message!
