Vintage Postcard depicting Whitman Dam Near Winona, Minn.

This is a vintage color-printed postcard featuring an aerial or elevated photographic view of the Whitman Dam near Winona, Minnesota, housed in a protective transparent plastic sleeve and resting on a wooden surface. The physical characteristics include standard postcard dimensions printed on cardstock with a glossy or semi-gloss colored front layer. The imagery displays a wide river landscape, dense green forests in the background, a long concrete dam structure spanning the water with small operational buildings featuring red roofs, and navigation locks alongside the structure. Notable text is printed directly onto the front borders: the upper right margin includes text reading "WHITMAN DAM NEAR WINONA, MINN.", the lower left margin bears text reading "PRIEWERT PHOTO", and the lower right corner displays a code reading "6A-H549". Visible condition issues include slight yellowing or toning of the paper borders indicative of age, minor surface dust or particles trapped within the plastic sleeve, and light edge wear. The aesthetic is consistent with mid-20th-century linen or photo-chrome postcards produced for tourism and regional documentation. The identification rests on the clearly legible printed titles and marks visible on the face of the card itself, though no physical inspection or archival provenance has been performed to date the exact printing year.

Based on what I can see in the provided image, this is a vintage color-printed postcard bearing text that reads "WHITMAN DAM NEAR WINONA, MINN." along with "PRIEWERT PHOTO" and code "6A-H549". The card displays standard mid-20th-century postcard characteristics, including glossy colored cardstock and age-consistent border toning. However, I cannot verify from a photo alone the exact printing year, paper composition, or whether this is a period printing rather than a later reproduction. My value estimate of $10 to $25 assumes the attribution to a mid-century photo-chrome postcard is correct. General market demand for regional vintage postcards is typically modest, appealing mainly to local historians, topophily collectors, and ephemera enthusiasts. Condition heavily impacts value; the visible edge wear, paper toning, and particles trapped in the protective sleeve place this specimen in a typical circulated state. To confirm authenticity, physical inspection by an ephemera expert would be necessary to examine printing dot patterns, paper stock, and ink application under magnification. If this piece were determined to be a modern reproduction, copy, or replica rather than a vintage printing, the value would drop significantly to a nominal amount of $1 to $5. Value ultimately depends on physical authentication, and an unauthenticated piece of this type would typically trade at the lower end of the market.
