Four years (and one day) ago, Kevin Systrom posted the first ever photo to Instagram, then a new social network with an uncertain future and exactly one photo of a cute dog in its archives.
Taken a few months before the app launched to the public at large, the photo shows Systrom’s long-time girlfriend Nicole Schuetz foot next to he Golden Retriever puppy @dolly at the Taco stand Tacos Chilakos.
