Artist Alister Pearson has produced a new A4 print for the event based on the original artwork designs for the Target novelisation's three covers, by Chris Achilleos, Andrew Skilleter and himself. He'll be at the event to sign prints, proceeds of which are in aid of Help for Heroes; it can also be pre-ordered directly from the DWAS website via their Day of the Daleks event section, and these too will be signed by the artist.
Though the event itself is fully booked, there is an open autograph session at the end of the event at 5:00pm for those who wish to come along to pre-order the DVD on the day and have the cover signed by the guests, Katy Manning (Jo Grant) and Richard Franklin (Mike Yates) - it is also hoped that Scott Fredericks (Boaz) will be able to attend on the day as well. As with the print, a signed DVD can also be pre-ordered from DWAS online before the event takes place.
Full details on the event and associated merchandise/activities can be found via the DWAS website.
BBC ClassicDW have also released a clip from one of the special features on the discs.
