Q: I have colorful oil paintings of a girl and a boy that are 21 inches high and 8 inches across. The painting of the boy is signed Alvaro. What is their value and who would be interested in buying them?

A: Paintings of children with big eyes were popular in the 1960s and ’70s. Several artists made “Big Eye” pictures, which were reproduced and sold as art prints. Although some prints are made to look like original oil paintings, these are prints. Your picture of the little girl is by Ozz Franca. These two pictures by Alvaro and Ozz Franca are fairly common and sell online for $10 to $20 if framed.
