Vaughan Mason Fine Art is an art gallery and consulting firm located in Houston, Texas. We specialize in primary and secondary-market art sales, valuation, brokerage, and appraisal services for private, corporate, and institutional clients. Our client-focused services are designed to manage the long-term needs of collectors at all levels.

We help people who have never bought art before become confident collectors. On the other end, when it’s time to sell, we work with clients to liquidate objects and even entire collections. Along the way, we desire to build a relationship of trust and care. Our goal is to always do all we can to bring joy and reduce stress.  

The right art has the potential to hold value and become an asset. In some cases, of course, art increases in value. The market for art is always changing, and we understand the factors that contribute to the value of art. We have the tools to research works of art, and can offer simple valuation services for various uses.

For more formal needs, our fine art appraisal reports provide support for estate and financial planning, asset management, insurance coverage, damage and loss claims, charitable donations, equitable distribution, and potential sales. Our reports are compliant with the Uniform Standards of Professional Appraisal Practices, an organization established by Congress to determine ethical guidelines for professional appraisal reporting. For charitable donations of works of art exceeding $5,000 in value, our appraisal reports comply with standards determined by the IRS for Form 8283.

We are available for assistance in art collection building, brokerage, cataloging and research, and can act as a liaison with experts in matters of framing, condition evaluation, restoration, and authentication, whether you have a single object, or an entire collection. Vaughan Mason Fine Art is located at 3510 Lake Street at Colquitt in the Upper Kirby Galleries.
