Boy - that is the million dollar question....I doubt you'll get any reliable estimate, but...I would start with organizations and schools related to concept art - Art Center in Pasadena, Academy of Art, Society of Illustrators, etc. Are you limiting it to concept artists in entertainment media or including industrial design, vehicle, product concept art as well? Might also check ID magazine for resources. I'm sure others will have good resources as well.
Curious to see what you dig up...
What would Caravaggio do?
That owl was a total asshole. He always ruined these kid's days by eating their treats they so rarely got. I always figured they'd be some poor orphan kids looking for a place to stay, having found a single rotten lollipop off the ground in their journey, and they ask the owl how long it will last (to stave off the hunger) and the ASSHOLE takes their only source of food and eats it. And taunts them to boot.
Thanks a lot for the links. Yeah, I knew I'd have problems finding it, unfortunately a high school teacher doesn't accept, "WELL WHY DON'T YOU TRY TO FIND IT THEN?!" as an excuse...
So Elwell, that CRUNCH would be… what, the owl eating every concept artist in the world passed the number three? .... Dear Lord does that mean he and that naked boy are GIANTS?!
