Roy Lichtenstein included Blam in his very first solo exhibition. Military themes can be found in several of his pop art works around this time.
The artist uses his cartoon style to produce a feeling of action and excitement, similar to that used in Whaam. The viewer is left to worry about the pilot of this aeroplane, as it lies damaged from an aggressive attack.
Reds and yellows create alarm in our minds, colours linked to danger easily provide this sense of immediate fear. The cartoon style used by Lichtenstein makes the situation less real, though, than if it had been an Ansel Adams photograph or Picasso political painting like Guernica.
In this particular piece, the lettering is not really needed, with a clear narrative very evident. In other artworks he would use type to perhaps get across a character's thoughts which could not easily be done any other way, considering his artistic style.
These single pictures would be expanded later into multiple stage compositions, like Whaam.
