Was thinking I might get all the Guido Rosignoli books I've not got. Doubtless they're familiar to most, but I've now paused & wondered if there's any other better or more complete things out there that present mounds of insignia in such an accessible way? These ones. Blandford: Whoops... ordered book 2 before finishing posting this. Still, at leas those two are a set. Several more to look at.
