Does anyone know where I can find a decent resolution scan  or other image of an index to the 1:100,000 (30'x60') topographic series?

I just need something showing sheetlines and names, that I can colour in to show our holdings.

Geokatalog2 (630, ed2, 1997 p.8) had a reasonable one, but their red overprint showing which sheets they sold makes it pretty much unreadable when scanned.

Something like that without the red overprint would be perfect, as it's still readable at A3 size.

I can't find anything at USGS publications webpage or USGS store (only the state indexes for 24k topos). 

Bohme/Anson, and Parry & Perkins don't include one either.

Thanks!
