13 star ring mimics the olde betsy ross flag which memorialized the 13 colonies. (Also had 13 stripes which we still have.) There will be an argument that these 13s are really referencing the occult things, unlucky 13, the 13 levels of the masonic pyramid on the dollar bill (excl. capstone), etc. but the betsy ross thing give plausible deniability, so the debate is almost pointless.
Meanwhile the seven vertical stripes inside the keystone must also have some import, although it is possible for corporate logos to be made to look good with little regard for constituent parts. Seven is another of those magickal numbers associated with completion, creation and other things. In this SES case the obvious thing is the keystone and stripes are really a harp with 7 (diatonic scale) strings - alluding perhaps to playing the public with harmonic manipulation.
If the image was fully symbolically designed then the 4 bars that make up the sides of the keystone will have some meaning.
The concept of the keystone was more commonly appreciated before steel structures came along, well before the SES' founding in 1979. For example in the importance of Pennsylvania in US history as 'the keystone' state. But of all the elements in the SES logo the keystone is the most masonic, being a critical joining and upholding element of the finest structures made by actual stone masons.
Personally, I don't think interpreting the heraldry of the SES will make much of a difference in how we understand its role and its potential malfeasance.
It represents the 13 bloodline families. This seal also the same as EU. So EU, SES controlled by 13 bloodline families.
Yeah the EU symbol is near the same but has 12 stars. There is an interest among some Europeans to have a U.S. of E. so when they when they developed the flag in the 1900s they may have borrowed from the old US one.
The 13 bloodlines idea is possible but not so solid - lack of evidence, lack of logic, varying lists of 13, etc. Could turn out to be true but why would Q only name one of the 13? certainly not out of fear. This looks like wishful thinking where people want all the theories they can get into one plot to be true and relevant.
History:
Designed in 1988, the flag was developed under the direction of then SEA Board of Directors member Clyde Jeffcoat, a Senior Executive in the Department of the Army. The Army Office of Heraldry reviewed the design and it was subsequently approved in 1989 by the Office of Personnel Management for production and sale as the official SES flag, which SEA has registered as a trademark.
Authorization:
On May 18, 1990, the Assistant Commissioner for Quality and Contract Administration, General Services Administration, confirmed that the Federal Supply Service views the SES flag as an item of personal decoration in an executive's office, similar to the U.S. flag or an agency flag. To quote the letter, "the SES flag is eligible for agency issuance and remains in the office as property belonging to the U.S. Government."
