A scan of your business card as prsentation slide 1
Right at the start of a presentation I always create an opportunity for the speaker to introduce herself. What visual to use for this? Definitely not a boring bullet point summary of your CV. Put a personal image that describes something unique about yourself. It can be frivolous in an informal setting, and in more formal presentations, a scan of your business card ("so last century") can be a good background.
Apologies for blacking out spam-sensitive details.
