SVA students push the envelope just by entering the school

I'm assuming y'all know the English phrase "push the envelope", meaning to innovate, push the boundaries. So KNARF had this idea to remind the students of SVA what they were doing every day. Images of envelopes with custom-engraved steel push-plates were installed on the school’s doors.
The School of Visual Arts students literally “Pushed The Envelope” while entering and exiting.
Pun!
