Mid-century children's book titled 'A Visit to the New York World's Fair'

This appears to be a softcover children's book with a cover illustrated in a mid-20th-century style. The front cover bears the text 'A VISIT TO THE NEW YORK World's Fair' and 'by Mary Pillsbury.' It includes a graphic box stating 'THE OFFICIAL 1964-1965 NEW YORK WORLD'S FAIR STORY BOOK' alongside a logo consistent with the period's Unisphere branding. The illustration depicts the Unisphere structure with various children in stylized international costumes in the foreground. In the bottom left corner, the publisher's mark appears to read 'SPERTUS 400-69.' The book exhibits visible wear consistent with its age, including soft corner bumping, some edge fraying, and minor surface scuffing on the pink-toned cover. The artwork is consistent with early 1960s commercial illustration. While the markings suggest it is an official souvenir from the 1964-1965 event, this remains a stylistic attribution subject to physical inspection. The item is shown being held by a person, providing a relative sense of size as a standard thin-format storybook.

Based on my visual review of the image provided, the item appears to be a mid-century softcover children's book featuring graphics and text consistent with souvenirs from the 1964-1965 New York World's Fair. It bears marks consistent with being 'The Official 1964-1965 New York World's Fair Story Book' by Mary Pillsbury, published by Spertus. While the stylistic elements and the Unisphere illustration align with the period's commercial aesthetics, I cannot verify the item's age or printing status from a photo alone; a physical inspection is required to determine the paper quality, ink absorption, and binding integrity to rule out later reproductions. The item shows visible wear, including corner bumping and edge fraying, which significantly impacts the value in the ephemera market. Collectors in this category typically seek pristine condition. This estimate is based on the assumption that this is a period-produced souvenir piece. If it were found to be a modern facsimile or high-quality scan-reprint, the value would be negligible, likely under $5. General market interest for World's Fair ephemera remains stable among niche collectors of mid-century Americana. Because many of these mass-produced booklets were distributed during the fair, they are not particularly rare, though certain titles are more sought after than others. To confirm the item's status, one would need to check for specific publishing identifiers and compare the substrate to known period examples. The value provided assumes the item is a vintage product of the stated era, as an unauthenticated or modern copy would typically sell for less.
