What is SURTEX (Selling & Licensing Original Art & Design)?

Like many creative people, I’m looking at options for how to make a living from my creative work. A friend of mine attended SURTEX (Selling & Licensing Original Art & Design) and she has inspired me to look into the options. I took a look at my work and created a one page layout that, I believe, represents commercial potential. There are several artist, who’s work I admire greatly, that license their work; Catalina Estrada, Gina Triplett and Matt Curtius
