Learning from Roy Lichtenstein
I went into a Mitchell-Innes and Nash Exhibition titled “Roy Lichtenstein: Conversations With Surrealism.” A few things about the Roy Lichtenstein drawings I saw there interested me.
First, it became clear that Lichtenstein started his work by drawing or doodling on small pieces of paper. After creating a number of related drawings he would then select one or a number of the drawings he liked and create a larger piece.
The second technique I picked up from a Lichtenstein artbook that was on sale there (though I didn’t purchase it). Lichtenstein projected smaller images onto the wall or canvas and then used the projected image to create the larger work. I’d like to know more exact details about how Lichtenstein did this as I would like to try doing this myself.

You might be able to find an old-school overhead projector. My grandfather used to use one to project photos onto a canvas. It basically shines a really bright light on the work and then focuses the reflected light to project an image. Of course these days you would just use a digital projector. Or print out an oversized version on multiple sheets. I used to blow up photos this way and then tape them together, creating giant posters that went up in my dorm room.
