The Disneyland Resort (mostly Disney California Adventure & Downtown Disney) have one of the finest collections of Deco Echo on the planet, despite taking down Tower of Terror a couple of months ago. More evidence to come as time allows. Photo from my 12/05/2016 visit.
This costume is so far my most elaborate costume and it was such a stress and hell to make! I very much prefer making simple-ish costumes and focusing more on making the construction as perfect as possible..
