Can Anyone Guess The Contents of This 1970 Pack?

I had Harper on the mind today after watching today's Cubs-Nationals game.  Quite a box score for Bryce Harper - seven times up, zero official at-bats, one hit-by-pitch and six walks (3 intentional).  The Cubs walked him 13 times in the four game series.

The only Kellogg's baseball cards of a player named Harper both are for Tommy Harper.  Harper is the only player to appear on a Kellogg's card with the Pilots and then the next year with the Brewers.
Don Mincher was the only other Pilot in the 1970 Kellogg's set.  He also appeared in the 1971 set, but as a member of the Oakland A's.  Neither Harper nor Mincher appeared in another Kellogg's set.

Harper broke into the majors in 1962 and retired in 1976 while Mincher's career was from 1960 - 1972.

Back to the pack.  Tommy Harper, #74 of 75 in the set, is shown on the top of the six-card pack.  What can I expect to find inside?

If the top card isn't cracked will any of the other cards be cracked?

Answers sometime on Tuesday or Wednesday.  With my busy schedule I probably won't be adding pictures for now.  Once school and coaching end I'll find more time to add more new photos.
