This delights me. THIS IS NOT AN ORDER. Like, this is not a command, this is just a suggestion...ultimately, it is up to you. I am sure it was originally used to stamp non-order invoices at a company of some sort, but found now, out of context, it seems just right for stamping everywhere as anedote to authoritarian proclamations!
4 5/8" l x 3/8" x 7/8" d. Very good condition, copper I believe, on wood. Earlyish 20th century. Excellent font.
