At the end of 2016 April foolishness is this Letter Sorter For Nurses puzzle, that goes along with JSVB entries #1228 and #1229, which can be seen by clicking here and here. This is the inked cartoon I pencilled in JSVB post #1225, click here to see it.
I've blipped out the e-mail for the prize, but honestly if you can solve this then e-mail me at the address in my JSVB header and I will see what I have around here for prizes. You might be able to guess the final riddle, but for the complete puzzle it will help if you have some medical knowledge.
