The Energetic Innovation booklet with the four banknotes was produced in 2008. Two types of brochures were produced, each with a print run of around 500.The notes highlight the security features of the de la printing of notes: colour thread, tilt, colour, machine readable magnetic thread, UV, magnetic numbering, protection of quality. The four renewable energy notes are superb, utterly wonderful and in their own protected sleeve. The recent auction have seen a huge spike in the demand for these notes and to have one of the brochures on offer is a rare thing indeed. The Wind power note alone is being offered at £65 by main dealers. To have all four in such a presentation folder is a wonderful offer.
