If you’re a designer yourself, most of these postcards should ring a bell. Irish graphic designers Mark Shanley and Paddy Treacy, in collaboration with other ad creatives, designers, animators, directors, illustrators and more, created this ”Sharp Suits” series, based on their “favorite worst feedback” from clients.

The creators say that the series has raised thousands of euros for charity – and must’ve provided the designers with a great outlet for some of their frustration. Check out their ironic series – they’re funny even if you’re the one hiring the designers!
