This button is attributed to the 1926 Philadelphia Sesqui-Centennial International Exposition. The Sesquicentennial was essentially a public relations event intended to mark the 150th anniversary of the founding of America and 50th anniversary of the 1876 Centennial Exposition. Sadly, the exposition was not a great success. Opening day got rained out, and far below expectation. The fair went into receivership, and the assets were auctioned off.
