1970 Topps Baseball Forum

I just completed this 24 card insert set today after previously overlooking it during my '70s set building.  Does anyone remember collecting these from wax packs?  Were they available in all series from the 1970 set, or just particular series?  

The first packs of cards I (vaguely) remember buying were in 1969. I was 8. I remember buying a few packs in 1970 and seem to recall a folded poster included. I don't remember the booklets or the scratchoff inserts. My vivid memory of the 1970 packs was that it seemed every single one had either a Lou Brock or a Roberto Clemente card. I kept 15 of each and then would throw the rest away. Sorry, but I was 9 years old and followed the American League, not the National League teams.
