It started with one bottle. Much like any collection, right? My MIL found this very large Listerine bottle that was once an old store display and carried it home on a train for me no less. After setting it here on my milliners table, it seemed so very lonely and the hunt started. Although I'm not 100% sure, I think I have finally acquired at least 1 of every size Listerine bottle there was, and now I have a happy little family.
