Text disappears after a drawImage(AffineTransform)

I'm expecting the text from the drawString call to stay painted on the canvas. The text appears for a second, but it is cleared once the image is drawn. The text reappears after the window is refreshed.

import java.awt.*;
import java.awt.geom.AffineTransform;
import java.awt.font.StyledString;

public class shear extends Canvas
{
    Image img1;

    public shear()
    {
        setBackground(Color.white);

        img1 = getToolkit().getImage("image3.gif");
    }

    public void paint(Graphics g)
    {
        Graphics2D g2 = (Graphics2D) g;

        g.drawString("400,100", 400, 100);

        AffineTransform at = new AffineTransform(1,0,.2,1,0,0);
        at.translate( 100, 100);
        g2.drawImage(img1, at, this);
   }

    public static void main(String s[])
    {
        Frame f = new Frame("Java 2D Test Product");
        f.setSize(new Dimension(800,600));
        f.add("Center", new shear());
        f.pack();
        f.show();
    }
}
