It's just Mubba. I thought to draw Mubba because I don't think i have another Mubba ACO (I should have at least one---no sense giving all the slots to Gene). ^^
Pencil...
The featured pencil is a rare 'Event' pencil by US Pencil Co.
It seems the pencil has a dollar-sign mark on it, but that's actually its maker's seldom used 'U S' logo (one letter imposed over the other).
Fun fact, after some unrelated correspondence with Bob Truby, my Event pencils (which I had recently sniped from eBay) came up in conversation. Truby expressed interest in one of my red Events (I have three different colors, the others being yellow and blue). I decided to give one of the red pencils to Truby, as a thank-you for his website (which has proven invaluable to me). :3
That I've noticed, Truby's not added the Event pencil to his site, but this isn't unusual (trust me). :p
Anyway, every pencil person (and, by now, my loyal watchers) should be well acquainted with Truby's site: 'BrandNamePencils' ...but just in case:
