Buying an original painting online means buying something you cannot physically inspect before the money changes hands. That is not a reason to avoid it — it is a reason to know exactly what questions to ask and what documentation should exist before you commit. Authenticity, in practice, is less about a single certificate and more about a trail of consistent evidence.
Ask for the paper trail, not just a certificate
A certificate of authenticity is only as good as who issued it and what stands behind it. Far more telling is whether the seller can show you the piece's history: who made it, when, whether it has been exhibited or reproduced anywhere, and — critically — whether the platform itself can vouch for the artist's identity, not just the artist's own claim. A reputable marketplace verifies artists before listing their work, which shifts the burden of proof off the individual buyer.
It is reasonable to ask directly: how was this artist vetted? Is their identity confirmed? Has this specific image been checked against publicly available sources to rule out a stolen or reproduced photograph being passed off as an original? These are not rude questions — any seller confident in what they are selling will answer them without hesitation.
Reverse-image and provenance checks matter
One of the more effective, low-friction checks — and one increasingly built into serious marketplaces — is an automated reverse-image search run against every uploaded artwork photo. If a "one of a kind" painting's image turns up on stock-photo sites, other marketplaces, or attributed to a different name, that is a legitimate red flag worth investigating before purchase, not after. On Rasa Collective, every artwork photo an artist uploads is automatically checked this way, and any match outside the artist's own verified channels triggers a manual review before the piece is ever approved for sale.
What to check yourself before you buy
- Does the listing include real, specific dimensions, medium, and year — not vague placeholders?
- Can you see multiple photos of the actual physical piece, including close-up texture shots, not just one hero image?
- Is the artist's profile substantial — prior work, a consistent history, a real bio — rather than a single listing with no other footprint?
- Does the seller offer a clear return or dispute path if the piece arrives materially different from its description?
When in doubt, ask before you pay
Any legitimate seller — whether an individual artist or a platform representing many — expects questions before a five- or six-figure purchase. Asking for a video walkthrough, an additional angle, or written confirmation of provenance costs you nothing and costs a genuine seller nothing either. The friction only shows up when something isn't what it claims to be, which is exactly the signal you're checking for.
