Welcome Girl Scouts, go away Door to Door Salesman! "Unless your selling Thin Mints, NO SOLICITING". This would be great for thehome front door on a small sign above the doorbell or on the glass door of a business.
Historically, the “Beware Of Dog” sign has been used by dog owners to caution strangers at the door. But times have changed, and dog owners (and their dogs) now welcome guests to the door in a more lighthearted and humorous way.
