How big is that burger

Here are two shots of the same burger. One is shot with the intention to make you believe the burger is small (compared to a match), the other is to show how big it really is (next to a pint ofGuinness).

What the first picture doesn't tell is is the true size of the match. It is probably 2-3 times the size of an ordinary match.

To use enlarged props to make another object appear smaller is probably a well known optical illusion. I just wanted to test it out for myself.
