Hey, thanks very much for these designs. Clever with the stethoscope images. #50 is the one that really intrigues me...combination of the stethoscope and online marketing. I get that 52 is the same concept but I think 50 gets it across better. Could you give me a few variations of #50? Maybe a couple of 2-color versions, and 1 with a little darker blue? Thanks, that's some great work!
