If I had to guess at the signature I would say it said “Johnson” !!

Doubt if you will find another with the same signature !! These people rarely make it as professionals !! What you have is typical class room/Bob Ross technique art !! Few years back most furniture stores and department stores had these paintings !! What we call starving artist works !! Most are about 16 X 20 in size although some were sofa size which are larger !! Using classroom technique lets these paintings be done in about an hour or slightly longer !! I can do one in an hour !! They are easy to do !!
