Hitachi Kidcolor Pompa Illuminated Sign - Lights Up, Showa Retro/Period Piece

This is a vintage illuminated advertising sign for Hitachi Kidcolor Pompa, a Showa-era (retro) piece. The sign measures approximately 880mm x 180mm x 180mm (seller notes this is an amateur measurement, so treat it as approximate). It is primarily black in color with some other coloring. The seller tested the sign and confirms it lights up normally (shown in photos 1 and 2), but states this is sold as-is with no future guarantee on the internal components such as the fluorescent tube.

Seller notes general wear consistent with age (scratches and dirt) and specifically calls out a vertical crack near the screw above the 'Hitachi' logo on the sign (visible in photo 7).
