Is blue boy painting VP64 on back worth something?

The value of a painting, such as "Blue Boy" (often attributed to Thomas Gainsborough), can vary significantly based on factors like its provenance, condition, and market demand. If "VP64" refers to a specific version or reproduction, its worth would likely be much less than an original painting. To determine its value accurately, consider consulting an art appraiser or auction house specializing in fine art.
