In the early years of the 20th century, one of the ways that enthusiasm for all things aeronautical found expression were in colorful chromolithographic postcards, like this Easter postcard featuring an intrepid, though slightly nervous-looking, rabbit who takes to the sky onboard a festive aerial egg balloon. The card was mailed to one Elinora in Frederick, Maryland by her cousin Louisa in April, 1911. Yes, a lighter-than-air bunny may be a little unlikely, but surely no more than a turkey piloting a biplane.
