Vintage Radio Station QSL Card for KOFI (not authenticated)

This physical item is a printed paper QSL card, commonly used by radio stations to confirm listeners' reception reports. The card is printed on off-white cardstock with dark brown typography and graphical elements. The prominent header reads 'KOFI VOICE OF THE FABULOUS FLATHEAD 1180 KC' alongside small logos for 'MUSIC' and 'NEWS'. The text details technical and historical information about the station, stating 'Montana's only Clear Channel, 10,000 Watt, Standard Broadcast Station.' It lists the studio address as '317 - 1st Ave. East (Box 608) Rt. 4 -- 3 miles East, Kalispell, Montana 59901' and notes it was 'Established in 1955, and operated since that time by The Flathead Valley Broadcasters.' Additional technical specifications describe the tower structure, including 'KOFI's No. 1 Tower, at 450', is the fourth highest structure in Montana.' The bottom left corner includes handwritten ink text reading 'Confirming your reception of Aug 8, 1978 at 11:39 pm - 12:05 am MST'. The card exhibits minimal age-related toning, minor edge wear, and faint handling marks consistent with mid-to-late 20th-century paper ephemera. The attribution in the name rests directly on the legible printed station name and address details visible across the face of the card.

Based on what I can see in the provided image, this paper ephemera item appears to be a vintage QSL card associated with radio station KOFI, bearing handwritten ink text documenting a reception report from August 1978. I can't verify from a photo alone whether the ink, paper stock, and printing techniques are period-correct, and I would need physical inspection to confirm material authenticity. My appraisal estimate of $15 to $30 assumes the item is a vintage, period-issued piece as suggested by the visible typography, cardstock toning, and edge wear. QSL cards from regional stations like KOFI generally appeal to niche radio hobbyists and history enthusiasts, though the broader market for such ephemera tends to be modest. What would be needed to confirm authenticity includes an in-person examination by a paper ephemera or radio history expert to evaluate printing methods, ink composition, and paper aging characteristics. If this item turns out to be a modern reproduction, replica, or copy rather than a vintage piece, the value would decrease significantly, likely dropping to nominal novelty value of under $5.
