# Yesteryear — Upstream Source Investigation

## Summary

No upstream source repository with UFO or Glyphs sources was found for Yesteryear. No source block was added to `METADATA.pb`.

## Investigation Notes

Yesteryear was designed by Brian J. Bonislawsky (DBA Astigmatic / AOETI). The FONTLOG explicitly listed three VFB source files: `Yesteryear-Regular-OTF.vfb`, `Yesteryear-Regular-TTF.vfb`, and `Yesteryear-Regular.vfb`. No GitHub repository was found under `astigmatic/yesteryear` or by searching for "yesteryear font" or "astigmatic font". Astigmatic does not appear to have a GitHub presence for their fonts.

## Status

**Skipped** — source is VFB-only; no UFO/Glyphs upstream repository was found.
