The most obscure Von Dutch piece of art I've never heard of, the credits for the terrible movie Angels From Hell, and the murals in the bars, and the garage ( I now consider this the most thorough Von Dutch blog on the internet)

From the comments in IMDB reviews:
"Von Dutch" Howards extensive artwork throughout the movie, including the opening credits. Bud Ekins's appearance riding the beautiful Triumph 500 Metisse certainly didn't hurt either!

Von Dutch's artwork, a usual, is Krazy! Check out the full-sized Harley chopper he painted on the barn!

Directed by Bruce Kessler, former race car driver at Le Mans, and team driver for Lance Reventlow's Scarabs, consultation from Sonny Barger

Was Von Dutch just showing off a chemistry formula? Or being an asshole?
H2 PO3 is DiHydrogen Phosphate (the ion that results from the first ionization of Phosphorous acid) and (NH4)2 C2O4 is Ammonium Oxalate: which is colorless, poisonous crystals.
So, as near as I can figure, this chemistry formula makes phosphoric acid. That stuff is used by Coca Cola to make it's soda have some tangyness

Ever heard of Blue Velvet? The Firebird Von Dutch striped? I never have before, and this seems to be all the internet has on the car

Von Dutch completed pin striping the well known "Blue Velvet" Pontiac Firebird in 1979, which is complete with two perfectly parallel pin stripes 16 and a half feet long down each side of the vehicle.

I just found the flying eyeball on the Maserati of Bill Krause, who was related by marriage to Von Dutch

What's driving me nuts is how damn long it's taking to search for better photos, of the car that won the 1960 GP at Riverside. You'd think there would be some online. Nope... not really.

a D type Jag that Bill Krause raced at LeMans and Riverside, painted by Von Dutch...

When Reventlow saw this Jag, he asked Von Dutch to paint the Scarabs

Von Dutch wandering around Lance Reventlow's Scarab racing sports car pits at Riverside in '58. The 1st race of the Scarab was in March '58, so that puts the pinstriping in the spring of 58 for the Scarab
