Hi daniL,
I'm not aware of any RWS stickers out there.
I don't know if you want the stickers as
visual reminders or simply as
one way to know which cards you've drawn. If it's the latter may I suggest using abbreviations instead of mini pictures? I use Roman numerals for the Major Arcana, Latin numbers for the pips, P, Kn, Q, K for Page, Knight, Queen, King and Wd, Sw, Ch, P for Wands, Swords, Chalices, Pentacles. Save you lots of time (instead of writing the complete names) and lots of money (instead of stickers).
