I know this isn't a very timely response... but regarding the water glyph symbol, it's found on all the cards. Marie White explains it here:

The triangle in a circle is what I use for a signature. It was a symbol I was always fascinated with, I dreamed about it as long as I could remember and I had no idea what it meant at first. I know now its a pretty widely used occult symbol for water probably because it is so feminine in relation to fire and the upside down triangle resembles womens genitalia. At first I used it on everything but as time went on I started tucking it away more in the painting and sometimes left it out altogether. I think because I felt that the work wasn’t mine alone but more something that came through me not just from me.
