Did you have those pages? I don't think there's much early stuff out there, as I said.
I posted my Boys' Ranch earlier in the thread; guide does disservice of saying #6 is Kirby splashes and center spread only, rest is Meskin. But well-known art dealer (I bought it in the 90's) swore it was Kirby, and every vet I've showed it to agrees. Meskin finishing Kirby layouts sure, but it looks nothing like straight Meskin.
Sinnott said the foolproof test would be the ears -- said Kirby could not draw them, and he was always fixing them. I may for my own satisfaction take it off my wall one day and show it to him.
