Towards the end of 1969, artists signed to Terry Ellis and Chris Wright's Chrysalis management company began to be favoured with a special Chrysalis label design - green with a red Chrysalis butterfly logo. Initially this applied to Jethro Tull and former Tull guitarist Mick Abrahams' band Blodwyn Pig. These early Chrysalis singles were allotted catalogue and matrix numbers in the main Island WIP and wipx series, respectively, and bore the legend "manufactured and distributed by island records basing st london" on the upper circumference of the label. Chrysalis continued to issue singles bearing Island catalogue numbers until Autumn 1971, after which the label broke away completely and began its own series of catalogue numbers in a CHS 2000 series.
