Looking for a star signature, about where to sign, depends on whether it is accidental or prepared when looking for a star signature. For example, in 2003, I met Andy Lau at the Deep Golf Course, and he got off next to me. I recognized him immediately. Nothing was prepared at that time. I only brought a hat, but fortunately it was white, so I signed it with an ordinary pen. My other friends signed my clothes notebook. This happened by accident. If you are prepared and know who the star is on the occasion, I suggest that it is best to have a photo or poster of that person. Of course, anything else will do, but if you don't sign the name of the star on your photo, the value will be different. If you choose a pen, choose a bigger and thicker pen for the big poster and a smaller pen for the photo.
