I know nothing about Ard Gelinck except that he lives in the Netherlands and he creates these wonderful collages of well-known people at various stages of their lives.
Read the images any way you want. Is Gelinck just showing the inevitable results of time and gravity and living, or is he illustrating the fantasy of being able to go back in time and teach your younger self all the life lessons you’ve learned over the years?
He’s charitable in his selection of subjects. There are no Dorian Greys in his gallery. Gelinck avoids the easy but cruel choice of pairing a picture of, say, the young Jan Michael Vincent with a contemporary photo, for instance.
I found these images on Bored Panda, where you can find many more.
