Proverb: "Don’t Judge A Book By Its Cover."

Meaning: 

You should not decide upon something based just on outward appearances.

History / Interesting Fact:

The origin of this proverb is fairly recent. The phrase is attributed to a 1944 edition of the African journal American Speech: “You can’t judge a book by its binding.” It was popularised even more when it appeared in the 1946 murder mystery Murder in the Glass Room by Lester Fuller and Edwin Rolfe: “You can never tell a book by its cover.”
