Bobc: I was hoping to get a chart with the same chords as my original example but I'll check out others in your links and see what I can find.

Jim: I need a page-size sheet.

Larry: similarly, I need a one-page at-a-glance reference.

When I'm helping these kids get started in playing along at (say) a family jam session, I give them this basic chord sheet for a reference as they learn:

I created it using the Personal Strum font, adding the other info myself.
I just wanted to put the more advanced chord sheet (shown in my OP) on the back of it.

Thanks all, I'll keep looking.
