Some of it looks hesitant. Ideal image calls for an extra close look. The "lM" transition appears a bit uncomfortable.
These signature styles must be after June 1967.
Yes, with the Mystery Tour car in the image. Apparently the photo was made from the original negative taken at West Malling Aerodrome during filming.
On first glance, if actually signed, with obvious scrawled traits, it looks fine to me.
Thanks Jim. The pen doesn't look like it took to the photo very well, but I agree that they appear genuine.
On first glance...yes.
