Here we have the foot, a foot soldier, so named because they walked and marched on their own feet, rather than being mounted on a horse.
The card tells us this is a foot soldier of Llewellyn ap Griffith, the first Welsh Prince, but of course this has been anglicised by Cope as he would have been known as Llywelyn ap Gruffydd.
He was also known as Llywelyn the Last, for he was the last native Prince of Wales, a title he held from 1258 until his death in 1282
By the way the a in the code stands for a variation, because these cards can be found with the text on the backs in a) black or b) grey.
And the really strange thing about the text is that every card is identical, only the top title changes
