1971 Topps Trios question.
 

Can anyone tell me how these trio cards were issued? We they in packs, a separate series, 3 per box, or 1 per pack. Any help would be appreciated.

Thanks,

Paul

aahh, My 2nd favorite set behind the 1970 FB glossy.

I'm 99.9% sure they came one per pack in these packs only

I remember it well...
 

1 sticker per pack. Rapidly ended up stuck on my closet door.

A large number of uncut sheets also surfaced in the late 1980's. I'm sure a number of them were cut up.

Great set and one I remember as a kid. Definitely one to a pack. I put a set together a while back, I love the black borders.
