The reason I set up Ace Jet 170 was because I have stuff stashed all over the house. Tucked at the bottom of a wardrobe, gathering dust on top, getting damp in the garage or (mostly) relatively unreachable in the loft. Ace Jet gives me a place to put it all, one place.
Of course, what's nice about having these little stashes all over the place is that every now and then I stumble across something forgotten. Like these two little booklets from Lund Humphries. The first being their type specimen booklet (the photos of that bit of type on the cover came out so well I felt the need to include all three).
There's no date in the booklets but I'd guess they'd be from the late 50s. Hot Metal days of course so fonts/sizes would be limited. A number of matrices give an overview of what was available.
The second booklet is their composition rules, compiled by the very great Herbert Spencer (which reminds me that I have Penrose Annuals to blog) who was responsible for these and this essential book for anyone interested in typography, amongst other things.
Read more about him here.
The booklet deserves close examination and, thankfully, backs up this.
