Thanks for the reply, but the ripped and stained version is different to the one Marty writes. There are two versions. Here are a couple of photos. I'm looking for a clear good quality version of the one in the photo here. Thanks though.
Two years ago, the original letter was for sale. Here's the picture from the auction catalog. The second picture was made with an AI image enlarger. The auction picture seems to be very dark. I would suggest you to make it brighter with an image editing software, before you print it.
