| Name the logo
You will need:
Collect as many different company logos as possible, from the Web or magazines, print them out or stick them onto sheets of paper, give each a letter of the alphabet.
How to play:
Each player has a sheet with the alphabet letters and a pen, they put their name at the top of the sheet. They find each logo and try to identify it. At the end of the party, or a specific time, the sheets are handed to someone else and marked for accuracy.
For a PR or Marketing company, include logos of your clients unless they will also be at the party, it might be embarassing if no one knows who they are.
