In 17 C.F.R §2.1, the seal is described as:

An American bald eagle in black and white holding the scales of balanced interests over a black and white wheel of commerce and a farmer's plow, also in black and white. These symbols are enclosed with an inner red octagon and a blue outer octagon representing traditional futures contract trading pits. Around the outside of the octagons are the words COMMODITY FUTURES TRADING COMMISSION separated by two stars from the year “1975,” the first year of the Commission's existence.

Public domain from a copyright standpoint, but other trademark-like restrictions apply. According to 17 C.F.R. §2.2:

(a) Fraudulently or wrongfully affixing or impressing the Seal to or upon any certificate, instrument, document or paper or with knowledge of its fraudulent character, or with wrongful or fraudulent intent, using, buying, procuring, selling or transferring to another any such paper is punishable under section 1017 of title 18, U.S. Code. (b) Falsely making, forging, counterfeiting, mutilating, or altering the Seal, or knowingly using a fraudulent or altered Seal or possessing any such Seal knowingly is punishable under section 506 of title 18, U.S. Code.
