As for myself, I can say that often a fragrance, song or television show will bring back fond memories of days gone by. One of those things is the Yardley fragrance collection. This is one of the few things that still exists today, thankfully. My mother often wore Yardley English Lavender as well as Yardley Lilac, and whenever I get a whiff of this scent it reminds me of her and of the positive events of my childhood. Here is a photo of a Yardley fragrance.
You can see how decorate and attractive the bottles were back then.
I saw this photo on the web and it also brought back some great childhood memories for me. However, even though this is a 1912 photo and way before "my time", it nonetheless brings back fond memories for me.
