Schrödinger’s Sleeveface

This has thrown a schism into Sleeveface land. It’s definitely an illusion involving a record sleeve. But does it meet the strict definition?

Let’s assume all you need is a person obscured – totally – and it would meet the definition of a Sleeveface. The person does not have to be visible. They could be hiding. But!

We can’t be sure if there actually is a person behind the sleeve, unless we disrupt the Sleeveface to check.
