Frank Grundeen artwork

Todays post is an item that was recently sold by Howard Lowery.
A piece of artwork done by Frank Grundeen at Disney. Possibly for a colleauge that just left the studio.(In the 1940's?)
His name appears to be Tony Pearson. Any familar names around the art? Myself I havn't heard of any of them. But then Disney employed tons of people that nobody have heard about.
Notice the sign to the right pointing to "Disney's Land"...
