I have two feldpost letters which i've had in my collection for many years despite not yet having them translated. Someone on here helped with a letter before so I hope someone can help decipher some of the text. Hopefully the result is something of interest to others on here. Please help!

Also, I havent used the forum in a very long time but want to get more involved again. Can anyone suggest the best ways to share images like the above. Attachments seem to be too large to upload hence using Imgur.
