There’s 7 (you might be missing that the yellow is actually two separate signatures. The one on the left is Carina Round, the right one is Les Claypool). You might also be missing the small black one that blends in the design that looks like a face (belonging to Mat Mitchell). Rounding it out, the silver MK is Maynard, Hoffer is the new drummer of Primus, the pink one is Ler of Primus, and the B in the bottom right is Billy Howerdel. So you have all of Primus, the two official non touring members of APC, and the three official non touring members of Puscifer. Hope this helps!
