AD above is from issue: MAY '74 page. 105
I just recently purchased approx.150 issues of this popular mag. and it ranges through almost complete years of '70 - '84.
Its slow going through them all, but my intent when purchasing them (for real), was to find old advertisement ads of LED / LCD watches. I found this ad within the first 4 issues I looked through, so I'm sure there will be plenty more to contribute.
Once I figure out where to post them all, I will start submitting them for all to see.
