These are some of the ampersands that caught my eye in a recent logo typography search. Just for fun, here is bit of history on the ampersand's origins:
An ampersand is a symbol representing the word "and". The symbol is a ligature of the letters in et, Latin for "and". Traditionally, in English-speaking schools when reciting the Alphabet, any letter that could also be used as a word in itself ("A," "I," "&" and, at one point, "O") was preceded by the Latin expression "per se" (Latin for "by itself"). So the word ampersand is a corruption of the phrase "and per se and".
Over time the way the ampersand was written evolved into the symbol we use today. In some of the examples above, the ampersands are interpretations of the modern ampersand symbol and others are more closely linked to the older Latin et.
