I do have that Mark Jones book so I have been reading up about this.
My problem is trying to work out what the cassettes looked like in 1972.
Phil Morris has kindly photographed two different cassette labels. Which one was published first? Which one appeared later on.
I do not know.
My gut feeling tells me the cassette on the left appeared first
The one on the right appeared later on when everything was reissued with the release of a subsequent album. Perhaps Selling England. From a rarity point of view the earlier cassette should be worth more. Genesis were not selling massively in mid 1972. They were a year later.
I do have both cassettes. Forever on the search for early Genesis cassettes
