I have an F. E. Flaherty mark from his stamp, but this is not only a hand-drawn mark, but a really nice example of Flaherty’s decorative concrete work in a driveway. Wish I could show you the whole thing.
Duffin & Riding did this entire street, so it’s likely that their well-preserved 1941 marks will never be erased. My previous example of this date was pretty precarious.
