Czechoslovakia: Unlisted airmail label

Here is a nice airmail label from Czechoslovakia. It's not listed in Mair's catalog of airmail labels as yet so don't have many information about it. Also the color of the label is difficult to describe. For me it looks like dark pink or fuchsia rose. Also it looks like printed on Parchment paper. Label de-pics airplane on front and lettering: "Letecký spoj zrychlil přepravu této zásilky" (Flights accelerated transport of the consignment)

Year: circa 1930's, Gummed. Günter Mair's catalogue no: - CSR-C-?, perforated 10 ¾ ,sheets,
