Largest collection of black markers in the world!

Tronoto based Stusio B.I.B (Black is Beautiful) set out on a mission to build the largest collection of black markers in the world. And if that wasnt enough he intends to draw each and every single one to scale. Allister Lee (the patient designer) calls his collection of drawn markers Black Marker B.I.B.L.E. The collection started in 2002 and by the beginning of this year has reached 523 unique black markers, and its till growing!

Now that requires some patience... what if he messes one up? does he redo it all over again??
