Autograph Signature on fragment of letter.

English contralto singer (1821-85). Signature on piece of paper of irregular shape (practically oval): roughly nine centimeters by four centimeters at the widest points. In poor condition: on paper discoloured by age and glue from previous mounting, and with hole and closed tear slightly affecting signature. Reads 'Your's very truly | Charlotte H Dolby', so presumably predating the singer's marriage in 1860.
