I got my hands on a type specimen book from 1889 and liked it alot. One thing confused me though and I was hoping for some help from my dear typophiles.
Almost every single '4' was drawn in this fashion(excuse my sloppy modification... but something along the lines of this):
Notice the angular cut, I can't remember seeing this in any recent design, or any 'traditional' (besides in this very specimen book) typeface for that matter either. 'Regular' 4's are AFAIK either closed or drawn with a cut that is not angular but horizontal.
Is this still used today, was it popular before, yaddfa yadda... please shed some light over my neophyte type knowledge. will ya?
