You're showing us the part where food goes (the top?) You can mostly tell by the handle.

I could tell by the thumb

I thought that would be easiest, but strange enough, the thumb was actually hard for my brain to figure out for some reason lol

Thumb and and shadows. Shadow is coming from the right (our prospective) under the pan, but the right part of it is shadowed,and that would be impossible if it was upside down.

it was rly obvious to me

Don't like this chief

Your thumb sort of gives it away

I can tell because I've held a cast iron skillet before and I'm not some retard fag that lives in an nyc pod

Good optical illusion
