Stunning fairground hand painted rounding board

Beautiful hand painted wooden panel from a circus or fairground, painted on front AND back! Approx 71cms high, 135cms wide and 11cms deep with the curve.
Stunning example of a fairground piece of art in a very art deco/Metropolis type style. It came to us in a fairly rough condition so has been treated for woodworm, which was long gone anyways, had some wood hardener applied in places, had loose paint and wood glue down, cleaned and then varnished to help protect it. It is still a bit delicate in places but definitely better than it was and would proudly hang anywhere.
Is curved as can be seen in the photos but not too obvious when looking at it from front on.
