Obviously, this sign on Venice Beach has been there for awhile, judging by all the tagging.

So, besides the misspelling of corned beef, they also have the apostrophe on the wrong side of the N at the bottom. And if my eyes don't deceive me, they have 'pop' spelt with a 2.

That makes sense.

Unless it's supposed to be '20 pcs' but has something stuck on it.
