For sale here is a very old leaded stained glass window panel at 30x13 in colors of cobalt and sky blue, clear, gold, green, and russet. There are no crack but the leading needs to be stabilized either additional c caulking, and straightening as it tends to bend with outsport.
There are two loops on the top if you hang it with the long 30 inches at top but you could easily take the wider version and you would see more stability.
