congrats to all those whov'e seen him and picked up a guitar pick ( wouldn't I love one of those!) My educated guess for the wording LB T1 would be that they are made for him by Turner guitars ( hence the big T) and the letter1....stands for Turner model One (1) as his guitars are his own specified make and unique to him...( well you seasoned guitarists will know what I'm on about anyways
) On the back of those picks, I'm guessing the line thru it shows that actually , he dosn't normally use them ( a bit of fun going on there, taking the mick..haha) Great pics too everyone.
