The "To Gordon" set has been around for a while. Early 1963 they were still looking for their autograph "identity". Helen Shaprio has said that while The Beatles were on tour with her in Feb. 1963...she see them practicing signing their autographs in different styles while on the tour bus.They finally settled on the style that were all know in the Spring of '63
The G and H are signed vertically and the rest is signed parallel with John’s signature, which gives it an odd appearance. On the forged sets, you can tell that that signature was copied at different angles.
