Hi,
I went to musium where many phonographs were displayed.
The founder of musium Mr. Son, he started collecting phonograph when he was a young boy. He was attracted by the sound and he spent whole life collecting the phonographs. Also, during the collecting, he also attracted great production of Edison. According to the musium, he collected almost one third of Edison's invention which is incredible amount.
Hearing the sound of the phonographs, I was also attracted.
