There appears to be a push broom, or perhaps a squeegee of some type, visible about the US flag, with the handle extending down below, to the right of the railing.
I looked carefully and didn’t see it. What would be the point of having a broom or squeegee out there if it’s so hard to see? If you’re going to display a broom, wouldn’t you place it in such a way as to allow it to be easily seen?
Here’s a pic of a sub displaying a broom. Notice how prominent it is. No need to play Where’s Waldo; you can’t miss it.
