I did some research and read on a thread here the story about Sean Cavanaugh’s SoftMaker. And whilst doing more research I found this on another thread
“Typeshop Collection”, which, as it seems, is the former Quick Brown Fox “Serials Typecollection”, which is the former Brendel & Pabst “Serial Type Collection”.
So what's the story with TypeShop, are they both reselling old URW typefaces? And if ‘Serials Typecollection’ is from TypeShop, why is SoftMaker using the ‘Serial’ suffix? And who are Brendel & Pabst and Typeshop (the description on myfonts didn't explain what I would like to know)?!
