Thank you very much!
Your idea is really BRILLIANT but, I have to say, I saw it (the man leaning on G) only after I read your explanation. When I saw it, I was really delighted, but until then I though there was an "i" or some pharmacy symbol (in Italy, contrary to most other counbtries, the caduceus is used more often than the Bowl of Hygeia, see
