To every article that is treated and to every roll or package of registered approved fabric or material a small label or tag shall be securely affixed, bearing the following information:
This information may be stamped, printed or stenciled on the article if so desired.
Concerns which treat or manufacture yardage goods may print or stencil their name, or the name of their fabric if registered, on the salvage (at least once every three yards) instead of affixing the label or tag as above.
