In April, 1960, postal officials determined that three magazines, ‘Manual,’ ‘Trim,’ and ‘Grecian Guild Pictorial,’ (hereinafter referred to as appellants), were non-mailable under
18 U.S.C. § 1461 as being obscene and as conveying information as to how and where obscene matter might be obtained. Pursuant to this determination, copies of the magazines were withheld from dispatch. Shortly thereafter an administrative hearing was conducted, in which appellants participated, which ended adversely to appellants. Suit for injunctive relief was then filed in District Court. Appellants' motion for preliminary injunction was denied. On cross-motions for summary judgment, appellants' was denied, and appellee's was granted. This appeal followed.
