Vintage Jewels Ballet Playing Cards NYC Ballet Balanchine NOS

Vintage Jewels ballet souvenir playing cards -- two brand new packs, still sealed and in the sealed cardboard box. One deck is green and the other white and both feature an intriguing pixelated looking ballerina figure in silver color. I haven't opened this so I am just assuming they are in unused mint condition but don't know for sure, and assume they're complete and regular playing cards. There's a slit in the cellophane on back of box and box shows minor soil and wear otherwise. According to Wikipedia, Jewels was created for the New York City Ballet by George Balanchine and premiered in 1967. I'm not sure when it ended at this ballet company.
