This is a wonderful collection of ephemera from the Hilton hotels. Each card features a color illustration of a hotel. One is the Conrad Hilton in Chicago and the other is the Statler Hilton in Detroit. The postcards measure 5.5" (14) by 3.5" (8.9 cm). They are in excellent vintage condition and have never been written on or mailed. This collection of vintage ephemera would be a perfect addition to your collection or to use for your next collage, scrapbook, tag, card or mixed media piece!
