Where the cards come from

Every picture is a scan or photo of a card in the owner's own collection: no seller photos, no listing photos and no grading company's images.

How the answers are known

Every card front is a scan from the owner's own collection, straightened and cropped to the card's outer edges.

• The answer is measured on the scan: the card's four outer edges and the four inner printed-border lines, each found along many lines per side, give the left/right and top/bottom splits.
• The measurement was checked against hand-placed lines before any card was scored, and every scored card was checked by eye with its lines drawn over it. Border types it can't measure reliably stay unscored.
• Cards not measured yet save your lines without scoring them.
• Your miss is the average of the left/right and top/bottom misses, in ratio points: within 1.0 is dead-on (and a bonus), within 2.5 sharp, within 5 close.
• Points are measured against the typical split: the middle left/right and top/bottom splits of the measured cards from the same era, a read anyone could make without looking. It scores 0, like Can't measure. You earn a point for every ratio point your miss beats the typical split's miss by, and lose one for every point it falls short, up to 3 either way.
