A system for displaying a sign on a vehicle, comprising:

• a main housing with an engagement protrusion that extends along a length of the main housing;
• a main housing sleeve with a recess that extends along the length of the main housing sleeve;
• a receiving housing with an engagement protrusion that extends along a length of the receiving housing;
• a receiving housing sleeve with a recess that extends along a length of the receiving housing sleeve;
• a winding mechanism coupled to the main housing;
• a rollable vehicle sign capable of rolling and unrolling on the winding mechanism, a first end of the rollable vehicle sign coupled to the winding mechanism and a second end of the rollable vehicle sign coupled to the receiving housing;
• wherein the engagement protrusion of the main housing is configured to slide into the recess of the main housing sleeve to couple the main housing to the main housing sleeve;
• wherein the engagement protrusion of the receiving housing is configured to slide into the recess of the receiving housing sleeve to couple the receiving housing to the receiving housing sleeve.

A method for displaying a sign on a vehicle, comprising:

• fastening a main housing sleeve to the vehicle using one or more first sleeve fasteners;
• fastening a receiving housing sleeve to the vehicle using one or more second sleeve fasteners;
• coupling a main housing to the main housing sleeve by sliding an engagement protrusion of the main housing into a recess that extends along the main housing sleeve, wherein the engagement protrusion of the main housing extends along a length of the main housing, wherein the recess of the main housing sleeve extends along a length of the main housing sleeve, wherein the main housing comprises a winding mechanism with a rollable vehicle sign, wherein a first end of the rollable vehicle sign is coupled to the winding mechanism;
• coupling a receiving housing to the receiving housing sleeve by sliding an engagement protrusion of the receiving housing into a recess that extends along the receiving housing sleeve, wherein the engagement protrusion of the receiving housing extends along a length of the receiving housing, wherein the recess of the receiving housing sleeve extends along a length of the receiving housing sleeve, wherein a second end of the rollable vehicle sign is coupled to the receiving housing;
• displaying the rollable vehicle sign across a portion of the vehicle when the main housing is coupled to the main housing sleeve and the receiving housing is coupled to the receiving housing sleeve.
