Printed on vintage accounting ledger paper.
Airmail graphics for label and stamp are from The Graphics Fairy, and were printed separately on label paper and attached to the airplanes like stamps. ("6 cents" was changed to "4 cents" in Photoshop.)
Postmark is a combination of several glyphs from a font called Dead Letter Office available free from daFont, altered in Photoshop.
Text typeset in Helvetica (all caps, outlined) and Trixie.
I had brainstormed ideas for invitations for my kiddo's Flying Machines party and came up with the idea of a paper airplane invitation that looked like Air Mail. A quick search revealed that it's not a unique idea. Boo hiss. I used this design from Country Living Magazine as a template for my planes, although the result is pretty different.
If you like these but don't want to invest the time to create your own, please e-mail me. I can create a version with your child's name and party details for a reasonable rate, with a 3-day turn-around.
Thanks for reading!
