Very Rare New Orleans Square Concept Art

When this piece showed up in my files, I was in shock. I do not recall having ever seen this before- and trust me, I have one of the largest libraries of Imagineering concept art in Disney fandom. I'm convinced of that, and people send me their rare pieces too. I know this is New Orleans Square at Disneyland. I know it is the Court of Angels. And I knowby looking at it that it is probably not the work of an artist like Herb Ryman. But maybe you can help me. I do not know the artist or the year it was crafted or even what it was used for. The left side seems cut off. Does anyone know more?
 

Herb Ryman's Court of Angels

By now, almost every Disney geek out there has heard about the beautiful Court of Angels becoming a holding area for patrons of Disneyland's expensive Club 33.  In the past, when Imagineers created these spaces for public usage as part of layering on theme elements, artist and legend Herb Ryman delivered an absolutely stunning pieces to sell the concept. Now, its just in the process of becoming available only to those guests in the upper echelon of tax brackets and social connections. Pretty appalling. 

For more discussion of the Disneyland of old and Imagineering's heyday, go to the discussion boards of WDWMagic and look for the thread started by former Imagineer Eddie Sotto. Fascinating stuff.
