I think at least half of all the scooter people I know own at least one Shag sticker that they have on their scooter or their car (so that you know they love scooters). If they don’t have a Shag scooter sticker, then they probably have a Shag tiki- or kitty-themed sticker.
This one is technically called the Shag Purple Scooter, but along with that purple is enough pink to make us happy. The large sticker is $3.50, and the small version is $2.00.
The best source for all things Shag is PosterPop.com, where you can also find the Shag Red Scooter (which is actually orange), the Shag French Scooter, and the Scooter Couple sticker, among many other Shag masterpieces.
