Hallmark Images for Purity, Gold, Silver and Platinum to print and save

It's so annoying when you see hallmarks and can't work out what they mean, so here's my answer which is a copy of a card I carry around with me sometimes.  The images below are sections from the card to enable them to be legible within the limitations of this feature.  Simply capture the images and reassemble in Powerpoint or the like for a full page.
