Retrofuturs is the moniker of Stephane Massa-Bidal. Stephane is a French illustrator that aims to combine the past, present and future into each piece. This particular series uses Helvetica majorly masked by objects that have been removed from photographs. The series’ aesthetic is similar to Mark Weaver’s while at the same time carrying its own.
I’d really like to know where the images came from. I would guess that they were used from a public domain archive or creative commons. The quality and compositions are these images are quite amazing.
