I'm not sure why or when it started, but for a very longtime now I have collected anything to do with vintage labels, particularly old apothecary jars. These are my only amber colored examples, but I have a rather large collection of the clear jars with labels under glass on my mantel. I also have a large collection of Dennison labels (and share them fairly often in the kits at Mercantile).
This also reminds me of the classic "It's a Wonderful Life" and how my heart skips a bit in the beginning when they show the back of the General Store (ever notice the apothecary bottles lined up on the shelves)?? Ah. . .one of my favorite Christmas memories (ha)!
