Bought 10 Shakespeare quotes postcards and have framed them individually and placed them around the house Love them, some are funny and some are deep and meaningful! Lovely background on some, excellent printed words. A couple of plain white cards with black print - very stricking

My order was probably an awkward one! I asked for a range of different fine-art prints, in postcard size. It was all freshly printed, delivered quickly and at a very reasonable price. Best quality matt finish I've seen on a fine-art print.

These cards are great quality, I use them as enclosure cards for my business! Hey are a little pricey but you definitely get the quality and professionalism! Repurchased a few times now and will continue to do so :). Beautiful, nice sheen on them, sharp and clear
