The mural, depicting a woman wearing sunglasses, covers the side of the Clemens Minimarket in Clemens Street.
Future Synth, created by the artist Void One, was commissioned by Brink Contemporary Arts as part of the Leamington Mural Festival 2021.
Void said: "I would like to say a massive thank you to the local community for the coffees and chocolates, as well as making me feel very welcome.
"Also thank you to Brink for the opportunity.'
Brink has thanked Travis Perkins, Dulux Decorator Centre and Beer Torrent for their support.
