To put a photograph on an egg, take one which is perfectly clean, sponge it over several times with 1 to 50 solution of table salt, dry, then sponge over with 1 to 12 solution of silver nitrate. Keep your fingers out of this, or they will turn fast black. Then take a black paper stencil or a small contrasty film negative, cut a hole in a piece of black flannel somewhat smaller than the negative, and tie around the egg to hold the negative. Then bring into light, print out, wash and tone and fix like any printing-out paper. And don't eat the egg, for chemicals will go through the shell.
