The AG logo is missing the correct alternate and ligature glyphs.

Hopefully, it is also missing a lawsuit over copyright or trademark rights.

The original (magazine) logo would only have worked in this context as an outline/cloisonné treatment—but that would have been quite interesting.

I'm actually not a fan of the actual Avant Garde logo. But I think the font Avant Garde, especially bold, is one of the best fonts ever made. Also, it's EVERYWHERE right now.

Lubalin was a Futura man. (He used it in the AG magazine after the logo had been made, before he extended it into a typeface.)
Here’s how I figure he first conceptualized the magazine logo:

Yeah those lopsided letters and the overlapping G and A totally ruin it for me. I'm glad they don't appear in the font. (though maybe they are there as alternates, not sure)
