The relation is sitting on a Coventry Eagle motorbike. These bikes were made from the end of the nineteenth century to about 1930s or 40s.
I looked at models on Internet and this model looked like a 20s model to me but I don't have the eyes of the real motorbike fan so if you are into motorbikes do you think you could identify the year of the model?
