Demonstrative Graphics

I'm a litigation graphics designer and I've lost my 8 demo charts from the 1990's. I good thumbnails but not the original Illustrator files. I'd like to have these images duplicated. You can simply add the images to a background and trace the chart. Technical accuracy is not at all vital. It's okay if some stuff like the anatomical drawings need to redone. I can also purchase images from Shutterstock. Attached are two of the thumbnails. I need HD rez images to drop into iMovie
