Perez, 35, has adorned a pedestrian underpass in the town of Gland with a portrait of a masked cashier scanning a bottle of soap and plans to add other figures, such as construction workers or dustmen, to the mural.
“I will especially pay tribute to cashiers. They are on the frontline with nurses and others,” he said.
He said his mural, adding colour to a “sad-looking wall”, was “for our everyday superheroes.”
Switzerland has recommended that its citizens stay indoors during the coronavirus which has killed more than 500 people and infected over 21,100 in the country, although it has stopped short of ordering a lockdown.
