You can buy photographs of old Hong Kong from Gwulo as prints ready for framing, or as digital copies for use in books, interior decoration, billboards, etc. For details, please contact David Bellis at:
Prints for framing
I use a local printing company that specialises in making high-quality prints. Let me know what size print you are looking for, and what type of photograph you want to have, and I'll show you what is available.
Digital copies for commercial projects
You've probably seen Gwulo's photos around Hong Kong already, as they've been used in advertisements, books, exhibitions, interior design for offices and restaurants, etc. Let me know what type of photographs you are looking for and how you plan to use them, and I'll let you know how I can help.
