A generation ago, few people had tattoos and those were mostly hidden beneath clothes. More recently, tattoos (both having and showing them) appear to have become common accoutrements of parts of modern society. Just walk down any street in summer temperature and you'll see all kinds of personal embellishments "engraved" on skins of various ages and colors.
Some of these ancient designs are going to be replaced (??) soon by more modern designs, like those also functioning as electronic signaling devices for your hand-held phone, tabloid, or whatever. Their big feature is supposed to be your ability to control your fridge, home lights, or other electric home gadgets--just by touching your shiny gold-leaf-tattoo as in the picture posted.
These new "tattoos" look really elegant; Egypt's Queen Cleopatra (69-30 BC) must be turning in her grave with envy. Hammered thin to a few thousands of an inch, gold leaf did not become widely available until centuries after her reign.
