well well well...
contacted an art and picture framing place in Palmerston North today who sell racing car art from a couple of similar artists. Seemed very keen to give my stuff a go as well.... May result in a few sales so definitely worth a punt.
Their address is: http://artandframing.digitalretail.co.nz/Products.aspx?path=Art+Shop/Auto+Art
Hope to see our art up there soon too eh?
