This image, the "Mad Scientist" had exactly the right amount of goofiness for the application I had in mind, and will be used in one of our flagship products. I'm pleased with the product, and I'm hoping I can find additional, suitable clip art in your catalog in the future.
I did encounter a technical issue when attempting to extract the image for editing and conversion to Photoshop, as it seems that there was a layer of several images in the PDF which prevented direct selection of the artwork. The workaround was to open the file in Acrobat Pro and export the page to JPG format and then import it to photoshop.
