I released the OldSchool icon set several years ago for the first time. It was a pretty big success. It hasn't been available on the web for a year. Now it's been re-released.
The OldSchool icon set contains 6 icons. Each icon is available in 16px, 32px, 64px, 128px and 256px size. These are free to use in both commercial and non-commercial projects. Enjoy and remember to share! I think they’re worth sharing.
