Look at the very fine detail (see new close-up photos) and check the paper quality and colour. The real prints are on off-white (very light grey - see comparison photo) and very thin paper that is prone to imperfections (creases and ripples).
If the paper looks too white or is in perfect condition, then that could be a sign that it is a fake. Also, the ink used on real prints should have a slight sheen and the reverse side of the print should have an embossed/debossed effect due to the screen printing and thin paper (see new photos). Received in person on the last day of the Banksy Gross Domestic Product installation in Croydon. The paper is very thin and prone to imperfections (ripples and creases that are less obvious in person) but I carefully brought the print home in the exact same condition it was received in.
