The 1955 Lego tower block

 
These are two versions of a tower block that appeared in Lego promotional paperwork in 1955. I used different windows in the first because I didn't have enough of the right type available, and then used the opposite type for the second tower once I'd found some more.

These towers are amongst the suggestions in the 1955 Byggebog (Building Book), as shown on Brick Fetish here (lower middle of the page). That illustration is clear enough to easily construct the building. It's also featured on the cover of a folder I'd seen, and which Brick Fetish also shows here.

(The other pages of these publications can be accessed from minute links at bottom right.)

For my photos, I've set the towers on the old contemporary town plan. As shown in the illustrations of the folder linked above, the Lego range only had Bedford trucks and VW vans at the time (the old type without windows which I didn't have when I took these pictures). The VW Beetles parked in my pictures were the first passenger cars to be introduced after that.

The rear of the building was probably supposed to be the same as the front, which I did on the second one I built. For the first one I again used different windows because those were all I had. These buildings would have been built from cellulose acetate parts in 1955, but mine are mostly ABS. Partly for strength, and also again because I didn't have enough parts in that type of plastic.
