This is Red Door 5 in a six door series. This cute little vertical door is different from all the others as it is divided into two pieces that open independently. I suppose this enabled business to be done by opening just the top portion, while the closed bottom kept people out. Again, the paint is eroding away revealing a palate of wonderful colors and textures.
Red door 4 has the number 3 stamped on it, as if to confuse you. Lit nicely, this old beauty has a significant amount of erosion, and much like the loose bricks at the bottom right, is fighting for existence.
