Appellants challenge their state-court convictions of knowingly selling obscene materials in violation of Birmingham City Ordinance 67-2.1 The district court, on the basis of the state court record, denied habe-as relief. We affirm.
Appellants first attack the ordinance. They argue it was unconstitutionally vague, failing to give them fair warning that their activities were illegal. They also advance the separate claim that the ordinance, as construed by the Alabama courts, fails to accord with the requirement of Miller v. California, 413 U.S. 15, 24, 93 S.Ct. 2607, 37 L.Ed.2d 419 (1973), that the proscribed sexual conduct be specifically defined. We reject these claims on the authority of McKinney v. Parsons, 513 F.2d 264 (5th Cir.), cert. denied, 423 U.S. 960, 96 S.Ct. 276, 46 L.Ed.2d 289 (1975), which dealt with this same ordinance and found these same contentions unavailing.2
Appellants also contend that the relevant publications were not obscene under the governing standards. Because appellants’ sales occurred prior to the decision in Miller v. California, supra, they are entitled to any benefits of the then-prevailing standards of Memoirs v. Massachusetts, 383 U.S. 413, 86 S.Ct. 975, 16 L.Ed.2d 1 (1966) (plurality opinion). They may also invoke any benefits of Miller. See Marks v. United States, 430 U.S. 188, 97 S.Ct. 990, 51 L.Ed.2d 260 (1977). The Alabama courts and the district court on this habeas challenge found these materials obscene under both Memoirs and Miller. That conclusion violates the standards of neither case. The decision is
AFFIRMED.
. That ordinance has apparently been repealed. See McKinney v. Parsons, 513 F.2d 264, 266 n.l (5 th Cir.) (quoting ordinance in full), cert, denied, 423 U.S. 960, 96 S.Ct. 376, 46 L.Ed.2d 289 (1975).
. The firm rule in this circuit is to adhere to a prior panel’s decision absent intervening contrary authority from the Supreme Court or our en banc court. Here the only relevant intervening authority is Ward v. Illinois, 431 U.S. 767, 97 S.Ct. 2085, 52 L.Ed.2d 738 (1977), which does not undermine McKinney. We thus reject appellants’ attack on McKinney and adhere to its holding.
