Back in the late eighties and early nineties. When the company I worked for had the Halifax contract, the text was a mixture of Gill Sans Extra Bold and I think one letter or two from the Futura family. But that was a long time ago when they were a building society and a property services. You know, when their signs were green and before that their signs were a nasty grey with red letters. They also had a 60/40 percentage of the white and red lines to give more red than white showing.
We used to run a Graphix 4b and System48 plus from Spandex back then. Oh the good old days. lol
