About the 1970 WRKO Music Surveys 

There were two versions of the Big 30  published in 1970.  (Type 6) Beginning the first of that year, the format of 1969's issues was changed to what we call 1970-Type A. It was a tri-fold, measuring 8-1/2" X 5-1/2".

Type 7: Beginning with the October 1, 1970 issue, WRKO issued a spiffed-up version of its BIG 30 survey series. "Type B," this was a flip-up, measuring 12" X 3-1/4" when opened.  As you flipped the survey open, the inside-top featured the photo of a current act appearing on the Thirty Survey.  The bottom half featured the actual music listing.
