Correct its not Louie nor Indiana or HA as far as I found. Here is the problem with these vases...they appeared in significant numbers in malls & were originally thought to be an unknown Louie line that was recently discovered, however the Louie vases known were all ribbed in the body & therefore that attribution was discarded. I am not certain they have ever been attributed, but admittedly I have not kept track of recent developments. They still can be found today in malls.
