I am grateful to my good mate DH for his complimentary remarks about the collage of bosoms of the 1960s. The lad wasn't even born then! So, just for you, DH, here's a collage of bosoms of the 1970s, and I would be grateful if you would not ask me how I came by them.
I should warn you though, my young friend, that the women portrayed here, if they were in their twenties at the time, are now in their late fifties, not that that should slow you down.
Or them, for that matter.
