Avant Garde and alternate E. Not sure about that S.

Very nice :) Thanks so much. I ’look’ at the alternates but don’t have a clue how to use them ... is there a guide or is it just ’common sense’ ... and I’m lacking ;)

I think this could be customised regular Avant Garde. The E is a bit different.

> is there a guide or is it just ‘common sense’

That’ll be common sense. Just substitute ligatures for all the letter combinations there are provided for, take a good long look at it and then remove the ones that are too much. The only rule with these things is: “If it looks good it is good”. ;^)
