* Oil paint on canvas: This was his primary medium. He often used a technique called "Benday dots," which involved applying small dots of color to create the illusion of shading and texture.
* Magna paint: This synthetic enamel paint offered vibrant colors and quick drying time, mirroring the aesthetic of commercial printing.
* Acrylic paint: Lichtenstein also experimented with acrylics, particularly in his later works.
* Plexiglas: This transparent plastic was used to create his "brushstroke" series, where he recreated the look of a single brushstroke in a magnified and abstracted form.
* Printing techniques: Lichtenstein experimented with various printing methods, including silkscreen printing, offset lithography, and giclée prints, to reproduce and disseminate his artwork more widely.
In addition to these materials, Lichtenstein often incorporated elements of comic strips and advertisements into his compositions, further blurring the lines between high art and popular culture.
