Need to sell aviation prints

A couple of years ago I posted some of my fathers pictures from his post war Spitfire 22 service with 615 squadron which we had ‘liberated’ from his loft. He had previously seen action on Hurricanes and Spit 9’s with 127 squadron from 1942-1944 (when he was shot down and hospitalised due to his injuries). The photo below shows him in the cockpit of one of the 615 Spits that I have just obtained in the last few weeks. Unfortunately he passed away just before Christmas and now my mother is selling the 5 bedroom house where she is living on her own to move into a small flat. We are unable to keep all of his possessions so I am hoping someone here can advise us how to sell some items.

I have 2 limited edition prints by Robert Taylor. One is “First of many” depicting Douglas Bader in a Hurricane climbing up to attack a Dornier over Cromer in 1940. I gather that there are a few versions of this print signed by Bob Stanford-Tuck, Jamie Jameson, Duncan Smith and Peter Townsend however this is one of the more rare ones that is just signed by Bader himself (actual signature). The other is “Duel of eagles” depicting Bader in a Spitfire being chased by Adolf Galland in a Me109. This print is signed (again actual signatures) by Galland and Bader.

I also need to sell a complete collection of 4 ornamental plates from Royal Doulton titled ‘Defence of the Realm’. They are all in immaculate condition and have their original box and certificates of authenticity. They comprise ‘Hurricanes over the Houses of Parliament’, ‘Lancasters over Beachy Head’, Spitfires over the Needles’ and Mosquitos over the Forth Rail Bridge’. On the rear of each plate it states that the limited edition has a maximum of 10,000 plates and these are set no 3159 ‘Presented to W/O A.C.White 127 Sqn’.

If anyone knows what the best thing to do with these items is could you please let me know. Many thanks and apologies for making a post that is not perhaps the normal style for the forum.

Ian
