Carl Judson, the creator of the Guerrilla Box, knows the joy of painting while out in the field.

He built his first portable pochade box while he was managing a cattle ranch in Colorado in the early 1980s. Not wanting the ranch hands to "catch him in the act," he invented a pochade box small enough to fit under the seat of his pickup.

When Judson did volunteer work in Central and South America, he brought his compact pochade box with him so he could continue his hobby. It wasn't long before he began to think of himself as a "guerrilla painter." Soon thereafter, with help from his son Arthur, Judson launched Guerrilla Painter LLC.

Today, Guerrilla Painter is the leading manufacturer of products for artists who travel and paint outside the studio.
