Although quite an old animation this one held quite a few surprises for me in terms of visual gags. The story is quite simple, if you could even call it that. I like the idea of the foreman being a high-brow conductor although his "construction mentality" shines through every now and then. The animation plays on the famous photographs of the men sitting on beams high above the city.
When the building collapses I was wondering if there was a general notion in those days that high-rise buildings might not be up to par with quality standards.
