The Art Guide: Identify, Authenticate, Value and Care for Paintings

Every Fastemy art guide in one place, from “what is this painting?” to “what is it worth?”

Updated

Art questions rarely come one at a time. Someone who wants to know what a painting is worth first needs to know who painted it, whether it is original, and whether the attribution holds. These guides follow that chain.

The famous-works section shows the same principles on masterpieces: why a Vermeer is a tronie, why the Last Supper decayed, why a woodblock print like the Great Wave exists in thousands of impressions.

Frequently asked questions

How can I find out who painted my painting?

Read the signature and any labels or inscriptions on the back, compare the style with artists of the period, and ask a regional auction house or specialist. An AI art identifier can suggest famous works and styles from a photo.

How do I know if a painting is an original?

Examine it with a 10× loupe: printed reproductions show a regular dot or inkjet pattern, while paintings show raised brushstrokes and uneven color edges.

What makes a painting valuable?

The artist, the security of the attribution, provenance, condition, and demand for that subject, period and size.

What is provenance?

The documented ownership history of an artwork, ideally traceable to the artist. It supports authenticity and legal title.

How should I clean an oil painting?

Only dust it gently with a soft brush if the paint is stable. Anything more — grime, varnish, flaking — is a job for a professional conservator.
