16 vintage postcards in accordion booklet form for Heidelberg, Germany published by Edm. v. Konig. The name of artist H. Hoffman appears on some of the 5-1/2" x 3-1/2" postcards. The postcards are black & white, but have a sepia quality. I do not know if this is merely a yellowing of the card stock. Excellent, unposted condition. The postcards are undated. Very good condition.
