Frequently Asked Questions

Yes. Please contact info@atelierzweig.com with the item you are interested in, your shipping destination, and any questions about condition, provenance, payment, or delivery. We are happy to assist with purchases directly.

All items are subject to prior sale. Because many items are unique, consigned, represented on behalf of another owner, or offered through multiple channels, an order is not final until confirmed by Atelier Zweig LLC. If an item is no longer available, we will cancel the order and refund any payment received.

Payments through atelierzweig.com are processed in the United States by Atelier Zweig LLC. Available payment methods may vary by order value, destination, and customer verification requirements. For high-value items, first-time customers, institutional purchases, or transactions requiring additional verification, we may request payment by wire transfer or another form of cleared funds.

Libraries, museums, universities, and other institutions may contact us to discuss purchase orders, pro forma invoices, deferred billing, or other institutional arrangements.

In some cases, yes. Because many items offered by Atelier Zweig LLC are unique, scarce, or high value, we may require shipment to the billing address associated with the payment method or to another verified address. For payments made by wire transfer or other cleared funds, we may be able to arrange delivery to an alternative address by prior agreement.

We may be unable to ship to certain P.O. boxes, parcel lockers, freight forwarders, or unverified third-party addresses where carrier, insurance, payment, or fraud-prevention requirements do not permit it.

For high-value transactions, first-time customers, institutional purchases, purchases through agents or advisers, or transactions involving regulated material, Atelier Zweig LLC may request identification, proof of address, beneficial ownership information, source-of-funds information, trade references, or other due-diligence documentation before accepting or dispatching an order.

Yes. Atelier Zweig LLC guarantees the authenticity of every item we sell and, where applicable, its completeness as described. We prepare descriptions in good faith and note material defects known to us, including significant defects, restoration, incompleteness, supplied material, ownership history, or other relevant features where applicable.

Each item is accompanied by an invoice, receipt, or written description, and where applicable a condition report, recording the description under which the item was offered. This documentation serves as Atelier Zweig LLC’s written statement of description and authenticity. If you require a separate certificate of authenticity for institutional, insurance, or collection records, please contact us at the time of purchase.

All items described as “first edition” are first impressions, first printings, or first issues, unless otherwise stated.

Prices vary according to condition, edition, issue, completeness, provenance, binding, presentation or association value, rarity, and overall collector appeal. A signed, inscribed, association, specially bound, exceptionally fresh, or notably complete copy may have a higher market value than another copy of the same title.
