A small railway stamp book featuring SL (steam locomotive) series stamps. Issued on June 10, 1975, by the Museum of Transport, Museum of Transportation Science, and the Japan Transport Hobby Association. All stamps are 20 yen and depict photographs or illustrations of SLs. With the abolition of SLs imminent, SLs remaining at stations across Japan were designed on postage stamps and stamped with the respective station's stamp. They were issued between 1974 and 1975.
