They're 12" square (actual print area 8") with a deckle edge on the bottom, and are printed on 250gsm Somerset Radiant White stock, signed and numbered.
They're at a special 'Goodwill To All Men' price of £27 inc. P+P for the UK, and $37 inc. P+P for US buyers (but make sure you order before 10th December if you're in the US), and are delivered in a sturdy tube. I'm throwing in one of my new Christmas Snowflake badges (resplendant with 10mm Swarovski crystal) with every pre-Christmas order.
They do look lovely, and I'm really excited about them!
