Pro-Action is a joint effort between the Association of Illustrators and the Society of Artists' Agents. The petition asks that contracts for illustration commissions be clearly phrased, fair and reasonable, and fully agreed with the illustrator in advance.
Pro-Action is calling for fees that "reflect the illustrator's investment of skill and labour, the use of the work and the scope of rights obtained."
The petition also states: "We ask that the moral rights of illustrators are respected. In particular, illustrators should not be asked to waive their right to receive an attribution (or credit) for their work or the right to object to derogatory treatment of their work."
Derek Brazell, who helps run the Pro-Action campaign, says: "In real terms, fees haven't gone up in the last 15 or 20 years. It's getting harder and harder to make a living out of illustration - creative industries can't really flourish unless people are making a living out of it."
