Here's a photo of the portable pop up sign I take with me to events around the country. It's proved to be a valuable piece of kit as when it's up, it grabs peoples attention and alerts them to the fact that there is a caricaturist present working in the room.
For me it's great, as I no longer have the hassle of introducing myself and what I do to each group of people at an event, and then trying to convince the 'shy ones' that it's a painless process to be caricatured, etc. All of this really does eat into my drawing time.
The sign speaks for itself which means people who wish to be drawn can come directly to me, and I can draw constantly, giving the customer maximum value for money without the time taking intros! Smart, eh?
