US Postage 1956 FIPEX Souvenir Sheet with Signature (unauthenticated)

This item is a collectible philatelic souvenir sheet from the Fifth International Philatelic Exhibition (FIPEX) held in New York in 1956. The physical item consists of a printed souvenir sheet on off-white paper stock featuring decorative red and blue scrolling border elements and typography. Prominently displayed in the center are two perforated postage stamps: a purple 3-cent stamp and a blue 8-cent stamp, both depicting the Statue of Liberty with the text 'U.S. POSTAGE', 'GOD WE TRUST', and 'LIBERTY'. Below the stamps, the sheet bears a cursive signature in black ink that reads 'Arthur E. Summerfield', accompanied by the printed title 'POSTMASTER GENERAL OF THE UNITED STATES'. The outer border of the sheet includes the uppercase text '5TH INTERNATIONAL PHILATELIC EXHIBITION, 1956' and 'NEW YORK, N.Y., APR. 28 - MAY 6', flanked by small red star motifs. Above this souvenir sheet, a separate single 3-cent purple commemorative stamp featuring the New York Coliseum is mounted on the album page under a black mount, labeled 'Coliseum' and dated '1956' at the top. The condition shows standard age-related toning of the paper, minor handling wear, and clean perforations on the stamps. The identification rests entirely on the visibly printed text and the layout typical of 1956 FIPEX philatelic releases. The signature appears to be that of Arthur E. Summerfield, though this specific signature is unauthenticated and presented purely as observed text from the image.

Based on what I can see in the provided image, this item is a collectible philatelic souvenir sheet from the 1956 Fifth International Philatelic Exhibition in New York, featuring an unauthenticated signature bearing the name Arthur E. Summerfield, alongside a mounted 3-cent New York Coliseum commemorative stamp. I cannot verify from a photo alone whether the paper stock, perforations, or signature are completely free from manipulation, and I would need physical inspection to confirm material integrity. The estimated value range of $25 to $50 reflects typical market behavior for 1956 FIPEX souvenir sheets in collectible condition with standard age-related toning. Because the signature remains unauthenticated, its presence adds speculative interest rather than a measurable premium; a fully certified autograph by a prominent political figure could shift the valuation higher, whereas an unauthenticated piece of this type generally trades near base catalog value for standard souvenir sheets. General market demand for mid-20th-century US philatelic items remains modest and steady among topical collectors. To establish a higher tier of value or confirm authenticity, this piece would require in-person examination by a professional philatelic expert and potentially formal autograph certification. If further testing were to indicate that this item is a modern reproduction, replica, or facsimile copy rather than a period-appropriate printing, the value would drop nominally to near zero.
