My program keeps generating four times?

For some reason when i run this program instead of outputting one card choice I get 3, sometimes four.

I'm trying to pick a name from the array list include it in the path, then output the image, you can see the result with the system out.

Heres the code:

public class Main {

public static void main (String[] args) {

    Main.createScreen();

}

public static void createScreen() {

    JFrame p = new JFrame("Angora Realms");
    p.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    GameGUI g = new GameGUI();
    p.add(g);
    p.setLocationRelativeTo(null);
    p.pack();
    p.setVisible(true);

    }
}

Here's where i create the GUI and also the paint:

@SuppressWarnings("serial")
public class GameGUI extends JPanel implements ActionListener {

public Button drawCard = new Button("Draw Card");

public GameGUI() {
    drawCard.addActionListener(this);
    add(drawCard);
}

@Override
public void actionPerformed(ActionEvent event) {

    Object cause = event.getSource();

    if (cause == drawCard) {
        System.out.println("Ay");
        repaint();
    }
}


@Override
public void paintComponent(Graphics g) {

    super.paintComponent(g);
    Cards c = new Cards();
    g.drawImage(c.getImage(), 0, 0, 450, 700, this);
    }
}

And here is where i choose what card to load:

public class Cards {

static Random random = new Random();

public static String getCard() {

    String card = null;
    String[] possibleCards = new String[] {"Cheetah", "Lion"};

    card = possibleCards[random.nextInt(2)];
    System.out.println(card);

    return card;

}

public Image getImage() {

    Image img = null;

    try {
    img = ImageIO.read(getClass().getResource("/dev/angora/images/plains/" + Cards.getCard() + ".png"));
    } 
    catch (IOException e)  {
    e.printStackTrace();
    }

    return img;
}

}

When I run the code I get 4 system print outs of a random variation of Cheetah and Lion. I've been told before that I'm actually creating 3 instances of my code somewhere, but I have no idea where...
