Supposedly signed in June 1964 on the way to their concerts in Denmark. Up for auction at DAVID DUGGLEBY AUCTIONEERS & VALUERS. Agreed Paul and Jimmy look OK and the John and George look to have been added at a later date in an unknown hand.
As odd as it seems, the “love” does kind of resemble John’s handwriting IMO. Could the Lennon and harrison have been potentially added by Mal or Neil? I feel like I’ve seen that variation of the “LE” in lennon somewhere, but can’t place it.
