Those are lovely and I'd give a thumbs up on both (though I appreciate authenticity isn't being questioned). The extra loop above the "O" in the second example is unusual
HI Mark! :) Indeed, my since sold 1993 Tonight Show (Nite Flights) ticket (I think an exemplar at Davidbowieautograph.com now) had that loop and a "best wishes" as well. Tiny on that ticket... It occurs sporadically as your fine posts illustrate.
