KɛdɩtʋUnknown early car on hilly road, possibly a Humber and the 1905 Isle of Man TT? (6057363652).jpg
Intriguing one this. Not sure about the model and year of the car. The registration plate appears to be simply M.I.B. There's also what appears to be a race number on the side.
I can see no markings anywhere to give any clue of the make of the vehicle.
Just a note on the quality of the scan - the particular textured paper seems to have created some marked speckled reflections which has made it much lower quality than the original.
