Unidentified Vintage Ballet DOUBLE Hand Signed Autograph Page

PFAS03    An unidentified personal hand signing from a vintage ballet autograph book which rests perfectly on the 5" x 4" souvenir undedicated and in outstanding condition. This needs identification but all this autograph album were ballet stars of the 1960s and 1970s and usually the Royal Ballet.  Someone with ballet knowledge can reap the rewards from this listing and please see all my other early ballet autographs from this same collection. Please note this is DOUBLE signed - there is a second signing on the reverse to identify too (please see image 2).
