If you could go back in time and tell your younger self something, what would it be? It’s a question most of us have pondered at some point. But since there don’t appear to be any time-travel mechanisms on the horizon anytime soon, would you settle for something a little more grounded? Like, say, a picture of you and your younger self hanging out? That’s what artist Ard Gelinck creates on his Instagram account @ardgelinck. Specifically, he gives this treatment to the photos of celebrities and other public figures, and his work is pretty impressive.

Start seeing double with these 11 examples of Ard’s stellar work. (Any ages listed are as of the time of writing; mid 2020.)

Honestly, I don’t know what I would say to my younger self if I could go back. Probably something true but unhelpful like, “it’s going to be easier and harder than you think.” At which point my younger self would probably punch me in the face. Maybe I’ll just try this photoshop thing instead.

What would you say to your younger self if you had the chance?
