That is something that everyone needs to do from time to time. It is also cool to look back on stuff like that!!
I know I always try to remember to take photos of different redecorating projects and it is really a blast to look at the photos from 20, 25, 30 years ago!! Kids like looking at that sort of thing too----"The blue chair used to have brown upholstery!!" and "OMG, what was I thinking when I bought those hideous rooster curtains!!!" It sure is interesting to see how your tastes and style changes over the years, as well as the areas where it stays similar.
