Actually the current Scholastic Art is about Lichtenstein. The lesson is
adapting a "masters" into his style. You simplify the work of a master (I
thought some of the coloring book copies would be a good place to start with
students-redrawn) and then fill in the spaces with primary/secondary colors
using grids, and dots, and such. It looks like a very interesting lesson.
Scholastic art has a site
but I checked and this lesson isnt included. Maybe you could find a school
in your county/district that subscribes to the magazine- if not, consider it
as a possibitlity- they are a great resource if you are fortunate enough to
be able to get them.
If this isnt clear, and your interested, let me know, I will try to synopsize
a bit better...
