A very old thread, but to avoid someone in the future reads this and thinks any of the following is accurate:

A wet day and by coincidence I was looking into this. I thought I recognised the "rod with snakes" it is still used as the symbol of doctors etc, it's the "rod of the Greek god of medicine Asclepius" the non-venomous snakes were used in the ritual of healing and were encouraged in the Greek temples devoted to this god. Hippocrates was the father of Greek medicine and the symbol is associatted with him and the Hippocratic oath which doctors still take.
This is a common error. It has nothing to do with the rod of Aesculapius. The latter has just one snake and is not winged. However, someone somewhere down the line lost the plot and started using the caduceus as rod of Aesculapius. Still, we are talking about transmission off post, so the intended item should be easy to identify.
It is a caduceus, the staff of Mercury (Hermes). The connection between this messenger of the gods and a postage stamp, I hope, does not require an explanation.
