This is a little different from my usual lists, which are primarily to catalog my Flickr collection; this is a list I've compiled of the original CVS locations from 1963 to 1969, when they were better known as Consumer Value Store. Store numbers and opening dates are included if I have them. If anyone knows any more information about these stores please feel free to comment!
