Photo 1 is a magnified image from ODOT # 3199-8-89 (Nov. 24, 1965) which has been rotated 90° for a clear view of the mail Pouch sign.
Photo 7 is a 1965 Ohio Dept of Transportation image which has been provided to show how clearly the Mail Pouch sign could be seen from US-33 before the tree and foliage growth became so dense that viewing the Mail Pouch sign from US-33 today is all but impossible. See Photo 8 (Google satellite image) to see how dense the tree and foliage growth is today (2022).
