AI Appraisal Estimate

This is a title page of an original medical textbook titled 'The Labyrinth: An Aid to the Study of Inflammations of the Internal Ear,' co-authored by Alfred Braun, M.D. and Isidore Friesner, M.D., both of New York. The volume was published by the Rebman Company, located at 1123 Broadway, New York. The typography and publishing imprint suggest an early 20th-century origin, likely around 1913. The page identifies that the work contains fifty figures in the text and thirty-four half-tones on thirty-two plates, indicating a high-quality scientific publication for its period. Physically, the paper shows a creamy-off-white tone with significant evidence of age-related oxidation and toning, particularly along the edges and the gutter where the page meets the binding. There is a visible horizontal crease traveling through the center of the facing blank page. The printing uses a classic serif typeface with a centered layout. A notable feature is the publisher's logo at the bottom, which features a caduceus wrapped in a decorative motif with the Latin motto 'AGE QUOD AGIS' (Do what you are doing). The page appears to be structurally intact with no major tears or ink bleeding, though faint foxing is present along the upper margin, characteristic of antique medical literature of this era.

I have examined the provided image of the title page for 'The Labyrinth' (1913) by Braun and Friesner. Based on the Rebman Company imprint and the specific typography, the item appears to be an authentic first edition of this early 20th-century otolaryngological text. The page exhibits period-correct oxidation, edge toning, and minor foxing, which are consistent with the paper stock used for medical texts of this era. The structural integrity of the paper remains high despite a horizontal crease on the facing leaf. From a market perspective, medical books focusing on specialized anatomy like the internal ear are collectible among medical historians and ENTs. Comparable sales for similar early 20th-century Rebman clinical manuals typically range from $100 to $300, depending on the condition of the plates and the binding. The value is bolstered by the presence of thirty-two plates, which collectors often value for their aesthetic 'half-tone' quality. However, the current market for general medical ephemera is stable but specialized, with a premium placed on works that represent pivotal shifts in surgical technique. This appraisal is based solely on the visual evidence provided. To finalize this valuation, a physical examination is required to verify the condition of the exterior binding, the presence of all thirty-two plates, and to ensure there are no interior library stamps or significant water damage hidden in the text block. I would also need to verify the provenance to ensure it was not part of a decommissioned institutional library, which can occasionally lower value. Without a physical inspection, I cannot confirm the suppleness of the paper or the presence of any expert restoration work.
