Some people see the whole world as their canvas. This definitely applies to Lyon-based artist Cal, who fills the most unexpected corners of the city with whimsical illustrations. He’s responsible for a number of otherwise dull urban spaces to be filled with humor and imagination. Cal has been active since 2016 and continues using his talent to breathe new meaning into things like iron plates, peeling walls, and abandoned objects. Take a look a the best of his work below.
