Glenda Model Sets 59 to 67 were not just toys or teaching aids. They were a manifesto for modular thinking, a brief shining moment when a company refused to sacrifice complexity for marketability. In their grey struts and red cables, they argued that a model should be a question, not an answer; a system, not a static image. For collectors and designers alike, these eight sets remain the gold standard of what the architectural model can be: a hand-sized universe of pure, constructive reason.
Set 59, released in the spring of 1962, announced a clear departure. Its signature was the "Uni-Joint" – a universal connector that allowed beams to intersect at 30, 45, 60, and 90 degrees without glue. This small plastic innovation was the key that unlocked the run’s coherence. Where previous sets required proprietary parts for each angle, Sets 59–67 embraced a grammar of repetition and variation.

By Set 67, Glenda had achieved something rare: a modeling system that appealed equally to the precocious child, the engineering student, and the professional architect. Yet, immediately after Set 67, the company pivoted. Set 68 introduced motorized parts and pre-colored “scenery” pieces (trees, cars, tiny figures). While commercially successful, purists decried the move as dumbing down. Consequently, Sets 59–67 became the “lost classic” era – too complex for casual toy buyers, too perfect to be improved upon.

Today, complete, unopened examples of Set 63 or Set 67 command thousands at auction. But more importantly, the design philosophy of these sets echoes in contemporary digital modeling software, where parametric components and constraint-based assemblies mirror the physical logic Cross encoded into plastic and nylon. For collectors and designers alike, these eight sets
