I draw caricatures live (on-site) and from photos by mail. I hope I can add that special element for which you are looking and I appreciate your interest. These drawings would be on 8.5x11" card stock and bagged in plastic when complete. Typically, I draw the head and shoulders in black and gray marker, which is about 30% faster than colored drawings. It takes me about 4-5 minutes per person depending on how quickly they switch out, sit still, etc. However, if you wish, I can draw with color markers. I use 3 chairs and can bring my tiny table (no bulky easel) to sit where the guests can watch the drawings evolve. There is a minimum booking time for some locations. No advance deposit is necessary, but, please pay in full upon arrival. I’ve been in business since 1982 and this experience helps me draw fast and true to the subject and I believe your guests will be delighted by my style (gentle humor not insulting).
