This was really strange pop art for me. Pop art is still famous and we may see in many places. This movement appeared in the mid 1950s and in the late 1950s in Britain and in the United States. This movement represents popular culture such as advertising or commercial art. Even though we see lots of bright and vivid colours in advertising or pop art, Alka Seltzer has not vivid colours and we see there are black, white, and gray. I mean dominant colours are pale. I think that the artist, Roy Lichtenstein used everyday applications of visual symbolization and “magnified” them. In this work, he pointed out the bubbles rising over the glass by scrupulously making abrasions extra places from a field of copy. By indicating the reverberating surface of the glass, he portrayed flat and black shapes which might be seen as graphitic, a misrepresentation, like dots, of the decreasing, line engraving effect of stuff advertising. He shows his graphic techniques and describing mechanical increasing traditions conduced to combine his work and create movement.
