Graphic Artists Guild
"The Graphic Artists Guild is a national union of illustrators, designers, web creators, production artists, surface designers and other creatives who have come together to pursue common goals, share their experience, raise industry standards, and improve the ability of visual creators to achieve satisfying and rewarding careers."
Through the Code of Fair Practice for the Graphic Communication Industry the Guild promotes equity between artists and buyers of graphic services.
The Guild also publishes Graphic Artists Guild's Handbook of Pricing and Ethical Guidelines which is the ultimate reference book for design professionals.
