(A) Ornamental or plain flat glass shall not be permitted to be hung from any canopy which extends over a public highway within the city, unless such glass is supported at all times around the entire edge by a sub-stantial metal supporting rib approved by the Building Commissioner; and such glass shall be limited to 100 square inches in area within any one set of metal supporting ribs.
(B) Exposed glass in any sign shall be permitted only when the area within any one set of metal ribs is not greater than 100 square inches for each and every piece of exposed glass.

(C) All metal supporting ribs in any sign shall extend over and cover at least 1/4-inch of the portion of the surface of the glass that is to be exposed.
(D) In case a picture or fancy display is to be used in an exposed area of any sign, not more than two open spaces of not exceeding 150 square inches each may be permitted in one sign.
