Any info on this unusual pottery canteen would be most appreciated

Can't find a maker's mark or signature.  Any thoughts on this?

Ignore the purple mark.  It's a lprice tag since I bought this at a thrift shop.  It will peel right off.

Any request for id help on pottery, must include a view of the bottom, because pottery is always id'd from the bottom up.

Also measurements. Could be a flask depending on size.

Possibly studio pottery inspired by Native American canteens. Very pretty.
