1933 Century of Progress Sc 730 & Sc 731 Souvenir Sheet FDC Beverly Hills Set

Note the small cover fault at the top right of the Sc 730 cover.

This is a nice matched pair of large-format First Day Covers (FDCs) featuring the complete 25-stamp imperforate souvenir sheets issued for the 1933 Chicago World's Fair. Both covers sport the official, highly desirable commemorative cachet produced by the Beverly Hills Philatelic Society.

• Year of Issue: 1933.

• Scott Numbers: Complete set of two oversized souvenir sheets:

  • Sc 730: 1c Green (Century of Progress, Fort Dearborn design in a full sheet of 25).

  • Sc 731: 3c Purple (Century of Progress, Federal Building design in a full sheet of 25).

• Cachet Producer: Beverly Hills Philatelic Society (designated in Mellone's  references under layout sequence #730-12 and #731-12).

• Cachet Design: A beautiful, two-color historical design. The top features a sweeping purple typographic arch reading, "American Philatelic Society Convention / Chicago Illinois 1933." The left-central vignette displays a detailed forest-green engraving of historic Fort Dearborn, underscored by the official circular seal of the American Philatelic Society (Organized Sept. 14, 1886). The bottom margin includes the printed type line: "American Philatelic Society Official First Day Cover / August 25, 1933."

• First Day of Issue (FDOI) Cancel: Each cover features a sharp, specialized circular convention handstamp reading CHICAGO, ILL. / AUG 25 1933 A.M. / A.P.S. CONVENTION STATION.

• Special Marking: Classic hand cancel horizontal killer bars extend from the convention dial to cleanly tie the oversized sheets to the right side of the heavy envelope. Each stamp is tic-canceled.

• Souvenir Sheet Details:

  • The Sc 730 sheet contains twenty-five imperforate 1c green stamps with plate number 21159 at the base.

  • The Sc 731 sheet contains twenty-five imperforate 3c purple stamps with plate number 21146 at the base.

  • Both sheets retain full outer borders displaying the line-engraved inscriptions: "UNDER AUTHORITY OF JAMES A. FARLEY, POSTMASTER GENERAL AT A CENTURY OF PROGRESS / IN COMPLIMENT TO THE AMERICAN PHILATELIC SOCIETY FOR ITS CONVENTION AND EXHIBITION."

🎡 The 1933 Century of Progress and the APS Convention

This matched set captures a major high-water mark for American stamp collecting during the teeth of the Great Depression, linking a global exposition with institutional hobby history.

• The A.P.S. Convention Station: The American Philatelic Society timed its 48th annual convention to coincide with the Century of Progress International Exposition in Chicago. To accommodate the massive gathering of collectors, the Post Office Department opened a dedicated branch station directly inside the convention venue on August 25, utilizing the specialized handstamp seen here.

• The Beverly Hills Philatelic Society: Based in Chicago, the Beverly Hills Philatelic Society was commissioned to design the official first day envelope for the host event. Their choice of the historic Fort Dearborn log fortress vignette offered a brilliant nod to Chicago's frontier origins, contrasting sharply with the ultra-modern architecture of the 1933 fairgrounds.

• The Pioneer Souvenir Sheets: Sc 730 and Sc 731 represent the foundational ancestry of the famous "Farley's Follies" era. Printed on flatbed presses, these were the first massive 25-stamp souvenir sheets issued by the United States, utilizing a completely imperforate format that required collectors to display the entire intact sheet to showcase its historical margins.

This addressed matched pair is a nice acquisition for advanced specialists in Chicago World's Fair history, American Philatelic Society (APS) convention ephemera, or classic Beverly Hills Philatelic Society premium cachets. Finding both large-format sheets on uniform envelopes with identical type-addressing and perfectly registered convention cancels offers exhibition potential.
