Rare vintage black felt-tip pen signature on an unevenly trimmed 1.5 x 5.5-inch portion of an L.P. cover, probably acquired in-person in the 1960s. In good condition. Note that the image of the star shown here alongside the scan of the autograph is not included. Cabaret singer and songwriter Portia Nelson was an occasional film actress, unforgettable as nasty Sister Berthe in The Soun of Music (1965) and equally unpleasant Sister Elizabeth in The Trouble with Angels (1966).
