Canadian cover from the English Zeppelin (technically not a Zeppelin, but a dirigible ) airship's Montreal, Canada flight. With Canadian 5c airmails, Montreal St Hubert cancel, and the R-100 Montreal 1930 cachet. Scarce, and with a great provenance: from the estate of the original collector, John Strauss, who collected these (and everything else Zeppelin) in the period as new issues / first flights.
