Original artwork description:

Ersatz
adjective (disapproving)
UK /ˈeə.zæts/ US /ˈer.zɑːts/

Used instead of something else, usually because the other thing is too expensive or rare:
"I'm allowed to eat ersatz chocolate made from carob beans, but it's a poor substitute for the real thing."
(Cambridge dictionary online)

Every self portrait is a substitute and the real thing is me. But every self portrait is something unique, so maybe I am an Ersatz of my self portraits as well. Every Ersatz self portrait is the Ersatz of every other self portrait of the series.

Confused? You're welcome.
