Wow! You're a few years too late. I was a weirdo for all things SUNSET BLVD during its original incarnation and collected everything. I had (in mint condition) ALL of the souvenir programs and Playbills (US and international) as well as CDs (cast recordings and special EPs). After 2 decades, I finally got rid of them. On that same purge period I got rid of hundreds of original Playbills (1920s to then recent) as well souvenir programs (tons of vintage original casts). The only Playbills and souvenir programs I've kept are all of the ones from Bob Fosse's shows (SWEET CHARITY, CHICAGO, PIPPIN, etc), and all of the FUNNY GIRL stuff (Barbra, Mini Hines and the tour's Marilyn Michaels).
