For hundreds of years people have been [badly] copying playing cards (see this article for more details) and I am proud to be part of that long standing tradition and offer my SVG playing card sets, well, a lot of them in fact, to the public domain.
The basic design is shown below and examples of some other decks, but you can make a deck to suit your needs (literally more than 10,000 combinations of decks available):-
Some variations of the sets you can make, ready to download now.
