I have owned this print since 1999. Phillips de Pury held an auction in September of this year, and a print (from the same limited edition of 50) sold for $2640 though the estimate was only $1000-1500. I will take best offer.
Info from Phillips de Pury:
And from Exit Art:

I bought the print portfolio directly from Exit Art and have had it, unframed and in pristine condition, this entire time. Mine is 17/50
