Recently, I was told about a talk, Grandmother's Storeroom: The Archeology of Your Family, which encouraged the keeping of journals about objects that make up our personal memory, very much like what an archeologist would do when they discover an artifact. How often when we find an old photograph or some long-forgotten knick-knack in the house, we can only wonder what the story behind them is.
This wonderful site called Significant Objects is all about the story behind what others might consider junk. And these objects are up for bid at eBay.
I find this recollection behind this toy toaster quite a good read.
