The actual greenfinch is roughly A5 (148 x 105 mm or 5.83 x 4.13 inches) but printed on A4 ( 210mm x 297mm 8.27 x 11.69 inches) paper. This gives you various framing options.
I personally oversee the printing process to ensure that all colours are a perfect match to the original. The inks are of an exceptionally high quality and are lightfast (archival), providing you with many years of rich, true colour. The paper is 100% cotton watercolour stock.
Your print arrives carefully packaged flat in a protective envelope all ready for you to mount and frame as you wish.
