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 !!
