From book FROG TO PROG: PINK LABEL LPS – Island Albums Part 1, by Stuart Penney and Chris Savage: 'The discovery of a 3rd design pink mono This Was gives the lie to the oft-quoted claim that this mix of Tull's debut was withdrawn immediately after release. The 3rd pink label did not come into service for LPs until October 1969, almost a year after the mono "This Was" is generally thought to have been deleted. Can the explanation lie in the murky and still unexplored waters of the great British export pressing? While the newly-unearthed white 'i' copy of This Was is certainly a UK pressing, the BIEM publishing legend on the label used to be seen more often on records originating in, or destined for, mainland Europe. Whatever, Island definitely pressed up a second batch of mono Tull LPs in late 1969 or 1970, baffling researchers, discographers and others who care about such things. The sleeve of this particular oddity is also unusual in that, though it has a similar design to those found housing 2nd and 3rd pink label pressings (as well as palm tree and early Chrysalis reissues), it features un-flapped white borders on the inside gatefold rather than the black borders found on all of those later pressings. Moreover, by the time the 3rd pink label came into use, Island was firmly established at Basing Street, yet the laminated sleeve of this anachronistic mono pink still carries the label's earlier Oxford Street address in large lettering across the back.'
