Vintage promotional print featuring the Portuguese training ship Sagres (not authenticated)

This item is a vintage rectangular paper print or postcard displaying a full-rigged tall ship, appearing to be the Portuguese navy tall training ship Sagres, anchored or sailing near a coastal fortification resembling the Tower of Belém in Lisbon. The background consists of a bright blue sky and deep blue water. The ship features multiple sails prominently adorned with the red Cross of Christ. On the left side of the image, vertical text in gold lettering is partially legible, reading 'EMISSORA NACIONAL DE RADIODIFUSAO'. In the lower right corner, there is a golden emblem containing the text 'EAN' and the slogan 'CANTANDO ESPALHAREI POR TODA A PARTE' surrounding the traditional Portuguese shield coat of arms and a radio wave graphic. The item shows visible signs of age, including edge wear, minor creasing, and slight surface fading. The overall aesthetic is consistent with mid-20th-century ephemera, likely produced for a Portuguese broadcasting or cultural organization. The identification rests upon the visible text, maritime iconography, and distinct Portuguese historical symbols present on the piece, though the exact date of production and printing process remain unverified from the visual evidence alone.

Based on what I can see in the provided image, this item is a vintage rectangular paper print or postcard displaying imagery associated with the Portuguese training ship Sagres and the Emissora Nacional de Radiodifusão. I cannot verify from a photo the exact printing process, paper composition, or exact date of production, and physical inspection would be needed to confirm these technical details. The piece shows visible signs of age, including edge wear, minor creasing, and surface fading, which are factored into my assessment. Assuming the working hypothesis that this is a period promotional ephemera piece matching its visual indicators, items of this type generally trade in the $40-80 range among collectors of mid-20th-century maritime and broadcasting ephemera, depending on condition and collector demand. If the item turns out to be a modern reproduction, replica, or copy rather than period ephemera, the market value would drop significantly, likely to the $10-25 range. To evaluate the piece fully and assess whether it is a period-correct printing rather than a later reproduction, an in-person examination by a paper ephemera specialist and potential provenance documentation would be required.
