The first 5000 copies of this album come with Pete Frame's Hawkwind family tree as a poster.
The original artwork featured an incorrectly wired plug on the reverse of the sleeve which was deemed a safety risk. Subsequent copies come with a supposedly removeable sticker over the offending image stating "WARNING - THIS STICKER MUST NOT BE REMOVED". Later pressings had the artwork simply blanked-out with no sticker.
