What's old is new again. I think this was introduced in 1984 with the Macintosh 128 or 1985 with the Macintosh 512. I know it was old hat in 1986 with the Mac Plus. People would trade flopies with icons or use ResEdit to design/customize their own. I still use a couple of folder icons that I designed on my Mac Plus and colorized later in System 7.
