This custom came about because of the lack of uniforms that are more normal on the planet combat in current days. Flag pole installation isn’t just to do with war however. Many organizations will gladly fly their pennants outside their headquarters, or outside their homes, to show that they have confidence in the cause or association.
Many standards or pennants will show something on them which everybody will associate with the cause or organization. For example, car dealerships will regularly have the logo of the car company gladly displayed there. On the off chance that they are sole dealerships for one make of car in particular, then they will fly pennants so individuals will recognize the car with that dealership.
For organizations, once in a while insignias that are associated with the group will be weaved onto the pennant. Freemasons are a genuine example of this where the set square and the ‘all observing eye’ distinguish them as masons. Although some would say that this organization would be in an ideal situation not distinguishing itself because of some negative connotations, the masons themselves will have none of that. They are pleased to be associated with the cause and as such will fly their standards when and where necessary.
