It would require a monumental effort to list every museum or gallery that have collections from the many artists who have acquired the title of Master Artist. Here is a very short list of some of the better-known museums.
Of course, just about every major city in the United States has its own museum of fine arts and all have excellent reputations for their collections. Here is a link to the Boston Museum of Fine Arts, Boston, Massachusetts.
Perhaps the most well known museum with its world-renowned reputation is that of the Louvre Museum in Paris, France.
And let us not forget another world-renowned museum here in the United States, The Metropolitan Museum of Art, New York, New York.
Wildlife
A previously mentioned nature art museum would be the Leigh Yawkey Woodson Art Museum, Wausau, Wisconsin.
Once again, many major cities in the United States have museums that “specialize” in natural history topics and include:
The American Museum of Natural History, New York, New York
The National Museum of Natural History, Smithsonian Institution, Washington
Another interesting museum to visit is The Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts. Not only does this museum contain one of the world’s largest collections of animal specimens, it was established with the help of Louis Agassiz (1807-1873), zoologist and wildlife artist from Neuchatel, Switzerland.
