My first thought was the 1971 Sport Hobbyist T206s, but as Steve notes, they didn't print Livingstone. The front borders are a little different anyway.
A while back there was a thread about T206 reprints and somebody mentioned a 1975 set put out by Nostalgia Press. I've never seen an example or a checklist. It's a bit tight on the timeline, but is still before 1977.
Anyone know what the Nostalgia Press reprints look like (and have a checklist for that matter)?
Regards,
Richard.
