"While the concepts for his images are often complex and sophisticated, the finished works are often compelling because of their vibrant mixture of naivete, wit, and whimsy. Ultimately, these warming characteristics invite viewers to relax and enjoy the often incongruous elements of his irrational images."
Since 1949, when de Mejo immigrated from Italy to the United States, he won immediate acclaim as a naive surrealist. His complete lack of academic training, coupled with an acute sense of fantasy, humor, and the supernatural, allowed him to naturally develop his unique style of naive surrealism.
De Mejo enjoyed many exhibitions at both museums and galleries in the United States and in Europe, including the landmark "Genius of the Naives" at the Grand Palais in Paris in 1982. His works have been featured in many magazines such as American Heritage, Architectural Digest, Harpers, Town and Country, Vogue, Travel & Leisure, The New York Times.
The two major books on de Mejo's life and art are Seldman Rodman's My America: Paintings and Comments by Oscar de Mejo (New York: Abrams, 1983) nd Robert C. Morgan's Oscar de Mejo, the Naive Surrealist (New York:Abrams, 1992).
