We'd Love to Hear From You

Yes — if a specific celebrity or item isn't currently in our eBay store, email us at mail@penmarkauthentic.com with your request. We actively source authenticated memorabilia and maintain relationships with trusted collector networks. We can often find specific items or add them to our sourcing list for future availability.

Visit our eBay store at https://www.ebay.com/usr/penmarkauthentic to browse current inventory. Each listing includes detailed photographs, condition descriptions, and pricing. Purchase through eBay's standard checkout for the combined protection of eBay's buyer protection and our own lifetime authenticity guarantee. We accept all payment methods supported by eBay.

Every item ships in professional, protective packaging with our Certificate of Authenticity included. If you're purchasing an autograph as a gift and have specific packaging requests, contact us at mail@penmarkauthentic.com and we'll do our best to accommodate. The Certificate of Authenticity itself makes for an impressive presentation alongside the signed item.

We are selective about acquisition — we only purchase items where we can verify provenance and authenticate the signature to our standards. If you have authenticated celebrity signed memorabilia you're looking to sell, contact us with details including the celebrity, format, how the signature was obtained, and any existing authentication. We'll evaluate and respond within 24 hours.

Our authentication services are focused on items in our own inventory — we authenticate every piece before it enters our store. We do not currently offer third-party authentication services for items not purchased from us. However, if you have questions about a specific celebrity's signature characteristics, we're happy to provide general guidance. Contact us at mail@penmarkauthentic.com.

For large orders, corporate gifts, or custom requests, email us directly at mail@penmarkauthentic.com with your requirements. Include the celebrities you're interested in, quantities, preferred formats, and your timeline. We can often accommodate bulk requests and may offer considerations for larger purchases. You can also call us at +34-603-503-502 for direct conversation.

We source items through verified channels including private signings, trusted collector networks, and documented public appearances. While our primary sales channel is our eBay store, we maintain connections within the autograph collecting community. Follow our eBay store for new inventory additions, or contact us to discuss specific interests and we'll notify you when relevant items become available.
