Old wooden flat roof ladder

Large old wooden flat roof ladder, 3.25 m long with 11 rungs and the 12th rung that holds the ladder on the roof, which is outside. The width is 45 cm and 6 cm thick. This ladder was used for roofing work, it is very thin and the joints are traditional, without nails or screws, and it bears some traces of paint and dents related to its past. Its colour is naturally greyed wood, so it can be painted after a simple cleaning and can be used decoratively either vertically or horizontally.
