Contact Max
The only reason I can think of that you'd want to contact Max Flex is so you could purchase a Tee Shirt, a hat, a canvas bag, a poster or who knows what, adorned with these and other illustrations.
Or... maybe you'd want to commission Max Flex to create some custom art. Who knows.
Regardless, your inquiry will not be shared, divulged, or otherwise gossiped about. Pure confidentiality.
