I’m as stymied as you on this one. Sure, Phil’s signature is a bit cramped and inward-directed, but the measurement is a weird thing. Did someone need to know who in the Dead had the biggest signature?
Billy’s signature was displayed at a picnic, no matter how many times he promised he wasn’t going to do that shit anymore.
Mickey’s was nice and plump, but curved to the right.
Keith’s signature was too big, actually: it never quite got hard, instead taking on the consistency of a Nerf football left on the lawn through the storm.
