Sleeveface

one or more persons obscuring or augmenting any part of their body or bodies with record sleeve(s) causing an illusion.

A video how-to that is fun to watch:

I think it's a fun fad, and keep thinking I should look thru my record albums to find some faces to try, but haven't done it yet - have YOU?
