I was 18/19 in '60-'61and cannot remember kids stripped football shirts or any at all. Even adults stripped were few and far between. I do remember seeing a Red/White stripped kids shirt when a kid. Material was knitted on a looms so there was a row between the stripes that was red knitted into white. I didn't get it, but cannot remember if it was because I didn't like the effect of the stripes. Probably the reason was clothes were rationed, as you'll remember, and more needy things to use coupons on.
Wednesday always seemed to have mascots throughout the 50's, where as blades never did or maybe almost never did, another point in my thinking of the Everton photo
Thanks again HBT always nice to fit in another piece of the Blades jig-saw.
