American Skyline was a construction set sold in the late 1950s and early 1960s by Elgo Plastics/Halsam Products Company from Chicago, Illinois.

[1][2] With an American Skyline set, its owner could piece together models of high-rise city buildings.

The set consisted of a collection of three different types of plastic parts; column segments, vertical panels (which included windows and doors), and floor panels.

Windows were single, double, triple, and a 7-window design as well as a unique bay style with single and double large open windows (which can also be used as room door ways to divide rooms if one wished).

The roofing and floor bases were basic thin plastic sheets with a checker board motif in white and brown to one side and blank white on the other.

They originally came in flat boxes, then Cardboard canisters with a metal top.

When Halsam became a part of Playskool the sets were discontinued, possibly because PlaySkool specializes in toys designed for toddler use, and these have small pieces that would have presented a choking hazard to toddlers.
