If kids see a Dons top hanging up next to the likes of Celtic, Rangers, Chelsea and Man Utd I think they're more likely to buy the Dons top and ultimately support them.
It's not as simple as supporting who your parents make you support. I know a lot of youngsters that went the opposite way just because. Kids can be stobborn and rebelious.
Kids are fickle. If they see Aberdeen along side all the big clubs it can only be a good thing for future support.
