Some people at Car shows

This is my display tell me is it clear enough should i get a plaque the size of my hood or are folks just stupid,all the info they need is there they have to walk past it to ask me questions and the answers are on the plaque. I don't mind talking to any one answering questions ect. Had a guy tell me he had a 65 cuda with a 318 he bought brand new i stated that maybe he was mistaken they did not come with a 318 but low and behold he had the only one. The one in front of my car is my new one i place it in the same place every time the other one is my before i changed it thinking it was too busy.
