Want to be an instant (Oil/Watercolor) artist? Remove the glass from a new picture frame and tape the glass down over the picture image you desire. Get oils or watercolor paints and paint the picture on the glass; using the picture as your 'copy guide (better than 'by the numbers').
When finished, let dry and insert it in the frame with non-painted glass surface on the exterior. Now you have a reproduction and you did it (who is to know that it is a 'mirror image').

Don't want to buy vinyl lettering? Don't have good handwriting? I came up with this idea after researching "reverse glass painting" projects.
