Description and research notes
Photographic proof of an official Letter Form prepared for the Commercial Banking Company of Sydney Limited. Produced in London in 1929, this proof records the full masthead Commercial Banking Company of Sydney Limited placed above a wide open writing field framed by ornamental guilloche and a large central rosette used to stabilize the printed background.
The proof was created through photographic reproduction, not through engraved plate printing. This method was commonly used for internal approval stages and for presentation to bank officers before engraving and production. The original cardstock mount confirms its role as an archival or reference model within the printer's workflow.
The layout reflects the design approach used for high security financial documents in the late interwar period. Australian banks often relied on London security printers for official documents such as letters of credit, correspondence paper, and remittance forms.
Certified PCGS 50 About New. The mount and photographic surface confirm its status as a workshop reference piece rather than an issued document.
