I hope the string is a lot longer than that. The one you've given is barely a fragment of header. But the following should work (it did partially with your example):

xxd -r -p file.txt file.jpg

So if you've got a whole bunch of these, we can script something up to process them all:

find -name '*txt' -exec xxd -r -p "{}" "{}.jpg" \;
