Currently enjoying the 1849 wood type specimen book from Wells & Webb, courtesy of the @RITTigers@mastodon.social digital collections:

I especially love the 100 lines pica (i.e. 1200 pt) Condensed Roman specimen where they could only fit one letter across an entire spread.
Kudos to RIT and the Cary Graphic Arts Collection for making such nice images and sharing them publicly.
