Individual cards are typically found with gas company imprint on the reverse (see Flash Gordon lot #2984). All five cards feature Mickey Mouse. Minnie and Goofy each appear on one. Sign has minor trace of corner tip wear and extremely faint crease line along left edge only noticeable upon close inspection. Appearance for display remains NM and cards are NM as mounted. In auction #201 we offered the 1¢ variant w/different cards and that sign sold for $2,000.
