Scott #C51 1960 Let Freedom Ring Airmail 10c and 50 similar items

This United States First Day Cover (FDC) features the Scott #C51 10-cent airmail stamp titled "Let Freedom Ring." The stamp was issued on June 10, 1960, as indicated by the clear postmark from Miami, Florida. The postmark includes the text "FIRST DAY OF ISSUE" along with a circular date stamp showing "MIAMI JUN 10 9-AM 1960 FLA." The envelope is unaddressed and bears a green printed cachet depicting a shield with the Liberty Bell and the denomination "10 U.S. AIR MAIL" along with the text "FIRST DAY COVER" beneath. The cachet has the initials "HF" at the bottom right, suggesting a hand-illustrated or less common cachet style rather than a well-known commercial maker. The cover is an excellent example for collectors seeking U.S. airmail first day covers from the 1960 era. The detailed Liberty Bell design on the stamp and the matching bell-themed cachet create a thematic unity that enhances its appeal. The typed addressee on the front is Joseph Simek of Gates Mills, Ohio, while the back shows a faint return address for William J. Holab from Cleveland, Ohio. This FDC is a classic piece suitable for those interested in U.S. postal history, airmail issues, and thematic collections emphasizing freedom symbols.
