Erection set—posts and panels

A modular toy construction system, comprising:

• a plurality of foundation pieces, posts, panels, and connectors;
• a base unit of length for foundation pieces, posts and panels;
• said plurality of foundation pieces, posts and panels being of assorted lengths, such lengths being multiples of said base unit of length;
• each of said panels having at least one panel edge;
• each of said panel edges having an edge width;
• each of said foundation pieces and each of said posts possessing receivers for receiving said panels;
• each of said receivers having widths equivalent to said edge widths for frictional fit of said panel edges in said receivers;
• each of said panel edges fitting securely into a receiver for frictionally joining a panel with at least one of said foundation pieces and said posts;
• each of said foundation pieces having a foundation top, a foundation bottom, a foundation inside edge and a foundation outside edge;
• each of said foundations tops having at least one top groove parallel to said foundation outside edge;
• said top groove comprising said receivers;
• a plurality of said foundation bottoms having at least one connector receiver;
• said connector receivers being the same width as said receivers;
• each of said foundation bottoms having at least one bottom groove parallel to said foundation piece outside edge;
• said bottom groove comprising said connector receivers;
• each of said connectors sized so as to fit securely into a plurality of connector receivers for frictionally joining a combination of said foundation pieces to each other;
• said foundation pieces and connectors operable to form stable combinations of said foundation pieces to each other;
• said foundation piece outside edges and inside edges having a plurality of foundation notches spaced apart;
• said notches comprising said receivers;
• each of said foundation pieces having a plurality of perforations extending from said foundation groove through said foundation top groove;
• at least one connector having an angle and an extended segment such that said connector is receivable in both said foundation bottom groove and at least one of said plurality of perforations;
• each of said post sides having a longitudinal post channel;
• each of said post channels comprising said receivers;
• each of said posts having a first end and a second end;
• each of said first post ends having a peg protruding longitudinally from the end of said first post end;
• each of said pegs having a width equivalent to said panel edge width;
• said pegs positionable in said receivers;
• a plurality of said posts comprising peg posts having a peg on said second post end;
• a plurality of said posts comprising notch posts having post notches in said second post end;
• said post notches comprising continuations of said post channels around said second ends;
• said post notches intersecting at the apex of said second post end;
• said post notches comprising said receivers;
• each of said pegs of said notch posts and said peg posts freely positionable in said receivers;
• said panels, posts and foundation pieces operable to form stable combinations of panels with foundation pieces and posts.
