Featured Jackson Pollock style painting signed

Here is another piece I picked up at my local thrift store, that cashier lady loves me.
I got it for $1.00.
The first name part almost looks like Johnny at first but then I see Joha???? And it looks like 2 arrows at the ends going upwards.
Anybody here have better eyes than me ?

Thank You

Billy D.

 

The first three letters definitely look like JOH to me, the start of the last name (assuming it's the last name) looks like an E or a G or Q to me (maybe even a B). There's a John Button who does abstract work??

 

Looks like John Clark to me

 

Perhaps it's John C. Clark for John Chem Clark?

I think MrNate has found the artist. The signature looks very similar and the artist seems to have very different styles of paintings looking at the three featured on invaluable. Only thing that bothers me is that the 12/04, is that the date? It's odd as people don't usually put the day. Might be a series, 12/64 maybe.

 

Thanks Nate, it's to bad I sold it at swap meet, darn.
