There’s nothing better than finding a little love note on your pillow, in your lunch or tucked inside a shoe. This public art project (Love Letter) let’s everyone in the city of Philadelphia discover one every day. The note writer is New York artist Stephen Powers. Growing up, he used the hometown walls of Philadelphia as his canvas. Decades later, he has come full circle using colour, walls and shapes to create this wonderful mural art project called Love Letter. Over a quick 3 weeks, he lead a team of 40 painters to transform and reclaim the space of 50 rooftop and street level walls with a little note of love. And we just love it. Here are some of our favourites. Spread that colour and love.
