Vintage eraser

I recently purchased A Collection a Day - a book by Lisa Congdon who is a San Francisco-based illustrator and fine artist. The book is the end result of a year long personal project by Lisa. In her own words "From January 1, 2010 to December 31, 2010. On each of those 365 days, I would post a photograph of one of my own collections or a drawing or painting of an imagined collection on a blog called A Collection a Day". Today I am featuring one of the many great collections she had in the book - vintage eraser. It amazed me that things produced such a long time ago are still get appreciated by today's audience, which is not the case with today's web industry; therefore what does it tell us? If you have the answer let us know.
