On my system ATCOakBold seems a good match. It came with my Quark 6 textbook. We had a lot of trouble with font substitutions on the HP laser with it, though.
Ariel Black looks close, and is old enough to be the right one.
Neither of those have the requisite point on the capital A. I'm a bit confused, actually, because I would swear that
is Futura, which does have the pointy A, but not at the weight that's used here. Up to about Medium/Medium Bold, Futura has exactly that capital A, but as soon as you move to Heavy (which this sample looks like), the capital A develops a flat top.
Most perplexing ...
Edit to add: In fact, if you type the word SUNDAY in Futura Medium, the letter forms are an exact match, right down to the points on the uprights left top and right bottom of the N standing clear of the main character height, plus, of course, that all-important pointy A.
However, as I mentioned, as soon as you change the weight to Heavy, the N and the A both develop flat tops.
Similarly odd is the fact that WOODSTOCK MUSIC and ART FAIR is pretty much an exact match for Futura BT BoldCondensed, except for the 'and' which has the wrong kind of 'a'.
Since this dates from 1969, I'm assuming that it was either set in moveable type, or possibly lettered by hand from book of type samples. I'm wondering whether this is either a Futura variant I haven't seen (entirely possible -- there are a
lot of them), or whether a hand-letterer used a lighter version of the face as the basis for the letters and then manually made the characters bolder whilst preserving the shapes.
