This 12th Dynasty wand amulet is at the Cairo Museum. I've made a small digital amulet using the Set image in it:

The hieroglyph at the bottom means 'amulet' and is a symbol of protection, often associated with the Goddess Tawaret, protector of women during childbirth.

Tawaret shows as a hippotamus and appears to the left of Set on that wand, as does the frog Goddess Heket, also associated with protection of childbirth.

(Also see more wands from the Middle Kingdom and learn more about the hippotamus' hopefully posthumous role in these!)
