FROST 127-247 $90.00
Cover mailed during the Graf Zeppelin's first 1936 South America flight. Was mailed on board April 21, 1936 during the Recife to Sevilla leg & is addressed to Pirna, Germany. Cover has a horizontal fold just below the two stamps & a small tear middle top. Missouri State Fair label seems to have no relation to the cover - I assume it was used for decoration.
Frost catalogue value $250.00.
