PER CURIAM.
The Court did not err in directing obedience to the subpoena duces tecum against the contention that it was invalid because, in the circumstances, its issuance constituted an unlawful delegation of power by the National Labor Relations Board to the Regional Director. N. L. R. B. v. John S. Barnes Corp., 7 Cir., 178 F.2d 156. Judgment affirmed.
