Modern Navajo Pottery?? I think

Found this one today too. I am not 100% it is actually Navajo, but I have seen similar ones with similar signatures. Most of these are more modern, I am guessing the 1980's???

I cannot make out the first name, but it is something and then "Navajo". Again, the outside is unglazed and the inside is glazed. A nice piece, definitely not made by a machine as the rim is imperfect. If anyone has a guess please let me know!!!!!
