I have now started a collection of Victorian postcards, since being in Berlin this has been surprisingly a good place to collect these. Five for one euro at the flea market at Tiergarten but you have to root around a bit! I have found some great images which have formed the basis of drawings.
I also discovered a book called "Fantasy Postcards" byWilliam Ouellette with a foreword by Babara Jones. This is a great book!
(I will put some images on of this shortly)
