Section 1.

The eighteenth article of amendment to the Constitution of the United States is hereby repealed.

Section 2.

The transportation or importation into any state, territory, or possession of the United States for delivery or use therein of intoxicating liquors, in violation of the laws thereof, is hereby prohibited.

Section 3.

This article shall be inoperative unless it shall have been ratified as an amendment to the Constitution by conventions in the several states, as provided in the Constitution, within seven years from the date of the submission hereof to the states by the Congress.

The 21st Amendment was one that repealed the 18th Amendment. This Amendment allowed alcohol now legal to use, make and transport.

This picture shows many people toasting, which happens usually at a special event or when something of significance happens. In this case, these people are toasting to the end of the 18th Amendment. 

This picture is also showing a reaction to the repeal of the 18th Amendment. "Good old days are back again!" is stating that the days before the 18th Amendment are back, the days when alcohol was legal.
