2008 Disney's Animal Kingdom at Savanna portrait by Larry Dotson

I have a portrait of what looks like a safari with a tour vehicle looking at a large tree with no leaves and two elephants and a giraffe. This is a portrait by Larry Dotson and on the back it has a lengthy description of the artist. At the top of the description it reads "Vacation Memories". I believe this piece of art came from a PGA event my Uncle was a part of. The description nots that Larry was chosen by the PGA to illustrate the beautiful 18-hole Poipu Bay golf course. This is one of many pieces of different types of history I am trying to learn about, find a value and hopefully sell. I'm lost at where to try to sell something like this because I feel like it has a lot of meaning behind it. Any information helps! Thank you!
