Art does not have the ability to talk to you and describe itself to you so an artist has to be good enough to portray the intended message to the viewer. Signs in art are more in the line of symbols thus it is for you to interpret the piece of work on your own. Signs can be along the lines of using words and the use of different shades of colour in the piece of work. Depending on the different pieces, the colours will symbolise different things. Like in road signs, the colour red is mostly associated with danger.
Assuming you enjoy the privacy of your space and do not want anyone to enter without your permission then you could get a poster sign that declares so and hang it on your door for people to see. If you want to warn people about something, a poster that states the specific danger for example: warning of toxic content then you just have to hang a poster explaining this to anyone who strays into that place. A poster always works well in this situation as they can be easily fitted at the convenience of the user.
So you saw a sign that impressed you and you are thinking that you must add it to your collection or you want to hang it for people to see and admire. What will you do? Simple, just get the sign in form of a canvas print, framed art or an art print.
