History of the Conlang Flag, from the Cleveland Public Library exhibit
Art leading up to the final flag design
The Conlang Flag was designed by Christian Thalmann, Jan van Steenbergen, Leland Paul, David J. Peterson and Adrian Morgan. It represents the Tower of Babel (translating Genesis 11:1-9 has been a tradition for conlangers) against a rising sun. It was released into the public domain. The versions above have been re-created at much higher quality by Paul Schleitwiler for the LCS, and are also released into the public domain. The icon files were created by Rebecca Bettencourt based on Paul’s SVG.
The LCS currently has a small quantity of flags to sell. If you’re interested in ordering a flag, bear in mind that this is a full size, all-weather flag: 3’x5′ knitted polyester, single side screenprint (1 ply), two sturdy hanging loops (called grommets) on the left side. Looks great from either side.
To order a flag, email email@example.com with a quantity and a valid mailing address. The Treasurer will then reply with a full price quote (flag plus shipping) and instructions on how to pay.
We currently have a few conlang flags left over from a previous order. If you ordered a conlang flag and never got notified or never received your flag, email firstname.lastname@example.org with the details.
Flags currently cost $26 for LCS members, $32 for everyone else. On top of that, we ask that you pay for postage. Currently (May 2015) postage for a first class parcel is about ~$4 in the US, and ~$13 outside of the US.
