Autism Symbol Where Can I Find Common PECS Symbols For Autism/related Disabilities?

Where can I find common PECS symbols for autism/related disabilities? - autism symbol

I know it was asking a strange way, but I've tried to keep the short term the problem. I am a short list of commonly used symbols PECS (Board Maker icons to create whatever), a small book for me all my folders to get ideas for working with children with autism and other disabilities. I try, a master in this field and I can do everything that I now learn, through the work and the Internet, and wondered if anyone knew where a list of common symbols. Thank you!
