The shop slogan is "Vintage Bumper Stickers and Other Ephemera". (items of collectible memorabilia, typically written or printed ones, that were originally expected to have only short-term usefulness or popularity)
I love the way Debbie describes the vacation stickers that she found in an old barn:
Some of the stickers are over 30 years old and all of them have never been used. Most of them are from roadside attractions. You know the ones we used to visit on family vacations before the big parks and corporate tourist traps.
I had a hard time picking a favorite sticker in Debbie's shop - but I think this one caught my eye! Can't you just imagine all the fun and excitement that went on in those dramas??
