Here is a incredible lot of old postcards.  The oldest dated one I found was from 1905.  But I am sure there maybe possible older ones.  Mostly all of them are in good condition.  A lot of them have not been used and some of them have been used with old stamps intact still.  I could not get them all pictured because of the limiting of photos.  Maybe about somewhere about just over half of them have been pictured.  I am guessing about 500 postcards give or take 50.  A lot of landmarks and nature.  Nice art to some of them.  This should keep you busy for a while.  Selling them all in AS IS condition regardless of what the description states or may NOT state.
