Collector's Guide

Whether you're buying your first original artwork or adding to an established collection, this guide covers everything you need to know about purchasing through ART & DAY.

1. Authenticity & Certificate of Authenticity

Works sold under direct consignment agreements with ART & DAY — including works by Matthew Rose, Ryosuke Cohen, Nicolas Journoud, and Alexandre Imai — come with the artist's hand-signature and a Certificate of Authenticity (CoA). The certificate includes: work title, year of creation, medium, dimensions, edition number (for prints), and the artist's signature. Please check individual product pages to confirm whether a specific work includes a CoA.

For limited editions, the edition number (e.g. 3/15) is inscribed beside the artist's signature.

2. International Shipping & Customs (DDP)

ART & DAY ships all works on a DDP (Delivered Duty Paid) basis. This means the price you see includes all import duties, taxes, and customs fees — there are no additional charges upon delivery.

  • Ships from: Tokyo, Japan
  • Carrier: Tracked international courier (FedEx / DHL)
  • Packaging: Each work is individually packed with archival-quality protective materials

3. Returns Policy

Returns are accepted within 7 days of delivery for works in original, unused condition with all accompanying documentation (Certificate of Authenticity, packaging).

  • To initiate a return, contact us via the contact form within 7 days of receiving the work
  • If a work arrives damaged or materially differs from its description, send us photos — we will arrange a full refund or replacement
  • Custom or special-order works are not eligible for return

4. Payment Methods

5. Framing

Most works are delivered unframed (artwork only) unless otherwise stated. We're happy to advise on recommended frame sizes and materials for any work — just get in touch.
Some works (including selected Matthew Rose collages) are available framed. Check the individual product page or contact us to enquire.

7. FAQs

Q. Can I request additional photos or measurements before buying?

Yes. Contact us via the contact form with the work title and we'll send additional angles, scale references, or any other details you need.

Q. Are Brain Cell sheets by Ryosuke Cohen unique?

Yes. Each Brain Cell sheet is a one-of-a-kind composition assembled from mail received from artists around the world — no two sheets are the same. Sets are identified by issue number (e.g. Issues 1071–1105).

Q. Can I send a work as a gift?

Yes. Gift wrapping and a handwritten message card are available on request. Let us know at checkout or via the contact form.

Q. What is the resale value of works?

ART & DAY does not currently offer a resale or buyback service. For market context on our represented artists, we publish price guides and collector articles in our Journal.
