Searching through my old slide collection I came across one of a J3-65 Cub marked "Grace the Ace" in large titles down the side - tucked away in the back of a Hangar in Lethbridge , Alberta back in 1980. here's the Photo
Piper J3C-65 Cub, N309H, Private
It had a notice in the Cockpit window saying something about holding a record for 80 Spins.
Have searched the web - with no result - for more info . Wish I had photo'd the notice.
Does anyone have any more info please ?
