Someone posted this........ Sorry it didn't take, anyway it was concession stand prices at Shea stadium 1967 to today.
Saw a chart of concession prices for all MLB stadiums from '75 and '76. As Mott The Hoople sang "those were different times. I used to load up going into Yankee Stadium. Sports Bar across from the old stadium for a Roast Beef, soft pretzel on the way in, coke from the concession stand, pig out during batting and infield sit back and watch Yankee Baseball. I'd hate to think of the cost today which may not seem soo bad had Yankee Baseball gone the way of the steam engine.
