Here's a very cool vintage atomic print shiny fabric! Made of a synthetic (feels like acetate or a blend), it's a dress or shirt-weight slightly textured weave. It's off-white with orange, green & brown spiny triangle motifs and confetti streamers or something like that :-0
 
178" long (that's 4 yd 34" length)  by 44" wide
 
Great condition with no noted flaws. Hasn't been washed or pre-shrunk.
