Vintage "Peter Pan" the Musical Book & Playbill

I swear I cannot find a date on either the playbill or the fabulous photo book from Sandy Duncan and Christopher Hewitt's Peter Pan musical on broadway. But I know I was circa 1979-1980 based on when they appeared together. Neither are signed by the actors, sorry. But they are cool together to keep as a keepsake so you "never grow old." The playbill has a rip on the front page, sorry. If you just want one or the other, you can offer up a bid. No problem. Typical aging with the books. Not mint.
