Ed Link Jr. Player Piano Roll Controls Sky Sign
By Karl Ellison
The Ed Link Jr. interview recording mentioned in 170215 MMDigest has
Mr. Link mentioning running an airplane that had a "Spaulding's Bread"
piano-roll style scrolling light advertising display on the bottom of
the aircraft wings.
Here is the mechanism in "Modern Mechanix" March 1934. Note the
nixie-tube style matrix design.
