Not only was I responsible for the design of these elements, I was also the project manager. I worked directly with the vendors to receive quotes, submit artwork, and purchase the final pieces.
Attendees to the trade show were given a game card at the Air BP booth. They then visited four Air BP FBOs and filled out information about themselves (regarding contact information, job type, and current, if any, connection to Air BP programs). Once appropriately stamped, the attendees returned the completed game card for a pair of monkey slippers.
These stamps were .75 inch round, custom-made, self-inking stamps purchased through Stamp-connection.com. I chose one of the available colors based on the FBOs' identity colors.
