Framed photographic print signed 'Peter Brock'

The item is a framed photographic print depicting a racing car, specifically a red, white, and black Holden racing car bearing the number 05 and various sponsor logos such as Mobil 1, Xbox, and NGK, captured on a track with a 'BIGPOND' banner in the background. The photograph features a distinct signature rendered in black marker at the upper right side, reading 'Peter Brock'. Below the photographic image, there is a metallic-looking plaque mounted on the matte board with text that reads 'PETER BROCK "King of the Mountain" 26 Feb 1945 - 8 Sept 2006'. The entire assembly is presented in a black frame with a thin gold inner trim and protective corner cardboard pieces still attached. The physical characteristics indicate modern printing techniques on photographic paper, encased behind glass or clear plastic within a standard manufactured frame. Condition appears to be clean and well-preserved with no obvious signs of wear, damage, or fading visible from the image. The attribution in the name rests purely upon the visually legible signature in the upper right portion of the print, as well as the memorial plaque context, though the authenticity of the signature itself remains unverified.

Based on what I can see in the photograph, this framed piece consists of a modern photographic print bearing a signature that reads 'Peter Brock', accompanied by a memorial plaque and a depiction of a Holden racing car. The presentation appears clean, well-preserved, and housed in a standard manufactured black frame with protective corner pieces still attached. I cannot verify from a photo whether the signature is actually by Peter Brock's hand, nor can I test the materials of the print or frame without physical inspection. In the current market, sports memorabilia associated with iconic racing figures like Peter Brock generally attracts steady interest from motorsport enthusiasts, though values vary widely based on provenance. The estimated value range of $300 to $500 assumes that the signature is accurate and the piece is as described. However, because signature authenticity remains unverified in this format, an unauthenticated piece of this type or a mass-produced reproduction would typically command a much lower value, closer to $50 to $100 for the decorative framing and print alone. To properly assess and establish authenticity, this item would require an in-person physical examination by a qualified autographs expert, along with any available provenance documentation or Certificate of Authenticity.
