Artist and redditor Elliot Frantz (u/thejehosephat) carved these amazing portraits into everyday pieces of corrugated cardboard. Using a simple X-acto blade and lots of patience, these relief-like portraits took Frantz about 16 hours each to complete.

On reddit, where these were submitted yesterday, Frantz says Hepburn was the most challenging as her hair would continually fall apart if he made the slightest incorrect movement. The accompanying Imgur album has already been viewed almost 200,000 times.
