The Human Body–Respiratory System Learning Chart

Simple enough for kids to understand and detailed enough to actually learn from it.

The poster was just the right size and the illustration easy to understand but the problem is when I took it out of the box which was supposed to protect it, it was torn and creased on one side. I would have returned it but the price is probably less than the mailing. If you can send another one, I really would appreciate it and my evaluation will be a lot better. Thanks
