Then, you purchase an equal size poster paper - my preference is yellow because it stands out - and you create whatever message you wish to say using large letters with black marker.
Once you have created your sign on the poster paper, using a razor or scissors, slice the bottom edge of the cellophane wrapping on the poster board, reinforcing the left and right edge with tape so that the cellophane wrap does not tear upwards. This allows you to reuse the poster board for future signs.
At this point, all you have to do is slip the poster paper sign up into the poster board where the paper will be protected from the elements by the cellophane wrap.
OK, here's where your ingenuity begins. You're going to have to affix a handle onto the poster board so that it can be carried high and proud.
My choice is an axe handle. But before you can mount the handle, you first need to add supports to the poster board. You need 4 strips of thin wood, preferably 12" long, and 1.5" or 2" wide and maybe a quarter inch thick. They will be centered on the poster board at the bottom, two on each side, spaced about 8" apart above each other and held together by whatever means you have in terms of nuts and bolts.
Now that you have the poster board braces in place, you now need to affix the handle.
Since you have chosen to use an axe handle, on the axe head end of the handle, simply sand down one side of the handle so that it is flat and can be centered on the two support braces you installed on the poster board. Drill one hole through the center of each brace as well as the axe handle and affix with whatever size nut and bolt you have chosen.
There you have it, a nice protest sign which in an emergency, can be converted to an axe handle for protection simply by bashing the sign on either the sidewalk thus releasing the sign or start with an attacker's head.......

Wrap cardboard tubing around the ax handle. If this is impossible, use thick piece of wood doweling to wrap cardboard tubing around. Otherwise, the cops will simply confiscate your axe handle/doweling as a weapon.
