Poland-based Zupagrafika has long made their fascination with Brutalism known, selling a range of pop-out and build concrete modernist structures from cities around the world. Now, the design studio has launched a new photo project for Brutalist fans to enjoy, that allows buyers to "remove the negative and discover the brutal charm of European suburbia."

Described as interactive photo boxes, the four packets—focused on the cities of Warsaw, Berlin, Moscow and London—come with 8 interactive cards, resembling Polaroid 55 films. Users are expected to pull the negative apart, revealing images of post-war modernist estates.

“Modernist housing estates erected in the suburbs of European cities after the Second World War have been ignored and neglected for decades,” says Zupagrafika. "Although they are homes to the vast majority of urbanites, many would rather they were invisible." Through these photographs, shot by Zupagrafika along with photographers Alexander Veryovkin and Peter Chadwick, users are able to uncover the hidden beauty of these forgotten and neglected, brutalist buildings!
