Aviation Art advice

I have a signed watercolour print of a Vulcan over Lincoln Cathedral which I no longer want. Can anyone suggest the best place to sell it? Clearly I'd like to get as much for it as I can however I have no idea how much it is worth so ebay/Gumtree etc are not really an option.
Thanks.
