Alto Recorder 2 (アルトリコーダー 2)

I bought it when I had been in US about twenty years ago for participating an academic conference held at University of Washington in St. Louis.



At that time, I had a presentation regarding my invention as poster session. Now the invention is well known as very unique material in our business field. So this Alto Recorder is very memorable article for me.
