I was a typesetter back then, i know!
It's probably a little harsh to judge the work done at that time by this advert, even 'pre computer' times. The industry went through so many changes around that time. When I joined the trade it was at the start of 'computerisation'. I worked with many guys who had spent their working lives on hot metal. The front end systems were specialised, hugely expensive code driven machines that looked as though they could have put a rocket on the moon, but probably contained the same computing power as an iphone. But it all changed very quickly and fortunately I got out before DTP really took hold and everyone was doing it on their 386!
Anyway, the advert, to my mind, looks as though it's been 'pasted up', done on the cheap. EG check out the word spacing, especially between the words AMAZING and BASS compared to BASS and WITH. Also a little too much space after the word 'pop,' which I think indicates manual paste up and last minute changes! They have RR/RL the three para next to the image but the last para is centred weirdly. I'm guessing the text was set to suit a different design and it's been hacked around! Just my opinion
