It’s rare to become enamored with entire photosets from an artist. It’s even more rare to fall in love with pictures for an ad. Last week, a set of pictures taken by photographer Tom Hussey made their way all over the internet. They were intended as advertisements for Alzheimer’s medication in 2010, but their poignant composition pulled at heartstrings all over the world. They are a sincere peek into the lives of strangers that truly tell a lifetime of stories in single images.
