Over the years when I show the Sprint I found that most signage used is either too large and detracts from the car itself or the sign has way too much information listed and most just walk off/by. I've also used the photo album but just like the sign most folks flip a page or two and move on.
I decided carrying a large sign not only is a PITA but not doing what I intended to. So I now have several 8x10 framed items that I sit on the core support.
I have a brief intro/history on the OHC along with reprints of actual ads from my collection.
I can switch it up real quick so it's not always the same ol same.
I have found this to work very well, as it's small enough to make them look closer and short enough to hold their attention and always leads to conversations rather than a breeze by.
This isn't anything more then my opinion but whatever you choose all I ask is Please Please don't use any of those stupid bumper dolls!
