The ampersand is a truly unique character of typography. Unlike most letters and punctuation marks, ampersands can be created in a variety of ways. The possibilities for creating an ampersand are limitless, and it's great because the word "and" is a huge part of human vocabulary. There's a high demand for the ampersand!
For a fun game, maybe on a Saturday or when there's not much going on in your life, try to count the times you say "and" in a conversation. Or, count the number of of times you type "&" in a message. "And" is a useful, prevalent and connective symbol.
Now that Twitter is so integrated in our lives, "&" is a great tool to help you stay within your 140 character range!
These particular ampersands can be found on Headjam's Pinterest page, and you can also find heaps of other fun typography.
