From an old-time collection put together in the 1950s, you will get 39 (thirty-nine) all 1927 or 28 First Flight Covers all first flights--no dedications, etc. Including pilot autographs and a variety of markings, though there is some duplication. All with Scott# C10 Lindbergh Stamp - very collectible.
There is one here that the Postmaster of Chicago Signed plus one with a really cool little bi-color label. I did not place any price on these three additional.
