TSR 1e AD&D module typeface

[Type O Negative]

Hi, first time caller, long time kerner here.

I'm looking to identify a typeface used on TSR's 1st Edition AD&D (later, colour edition) modules, used below the title. 

The sample is dated 1980 and isn't Futura as it has a distinct "1". I've run it through the usual font id websites, to no avail.

It's got me curious.

Cheers, Type O

Avant Garde Bold with a custom glyph for "1" it seems.
