How do you tell if a canvas painting is real?

To tell if a canvas painting is real, research using trusted online resources and published references. Learning about the artist and the type of work they produced can help you spot characteristics of their style, such as the types of brushstrokes they commonly employed and how and where they signed their work. You can then use these aspects as criteria for evaluating your painting. Another option is to have a certified appraiser or knowledgeable art dealer inspect your piece and give you an opinion on its likely authenticity.
