This is a set of items likely purchased through mail order, including four harmonicas, two harmonica performance cassette tapes, and a harmonica instruction book. The harmonicas consist of two Suzuki harmonicas and two Miyata harmonicas, totaling four. The instruction book contains sheet music and instructions on how to play. Due to their age and storage conditions, there is some staining, as shown in the 14th photo. The cassette tapes have not been tested as there is no cassette deck available to check the audio. Please consider this if you are not concerned about minor imperfections.
