I saved a 1963 Hawaiian long form (SEPT 6, 1963) on my desktop and it has the same curvature of the type-set but not the paper, so I don’t think that is uncommon, although other things are, such as Susan Nordyke’s BC has Honolulu, Oahu and BO’s has Honolulu, Hawaii on Town and State line and registrar’s name is different on Nordyke’s.
