Any ideas for the "Frank" here? I'm trying to repaint my Madone after an accident. Thought I might put my own name on the top tube.

I would use a substitute too.

Avant Garde  Suggérée par frd 

"A" is among the alternates.

Even better!

Could you make a suggestion for the "Made in Luxembourg" part? I suppose I should get that font too, just in case!

Hum, it's way too small and too "basic" to be absolutely sure, but I would say it's also Avant Garde (especially if you take a look at the "G")

I bow before your knowledge of all things fonts! :P
