I am currently searching for my old Doctor Who autographs that i sold (unfortunately) to black hole bookshop in the late 80's. I had all the Doctors apart from William Hartnell, and several companions, and would dearly love to recover these. The tell tale sign that an autograph was mine is that it was either dedicated "To Guy", like the Pat Troughton, a postcard with Jon Pertwees Autograph, or any other autograph that had been covered in contact. These were official BBC postcards by the way. I have recently re purchased all these autographs and would swap whoever has my originals or pay a reasonable fee.
