In 1965, one art critic, Vivien Raynor, observed that Krushenick "is now beginning to look Pop. Whether this is because he anticipated the movement and now looks more official, or because he's using acrylic colors, or simply because everyone to an extent becomes a victim of the audience's compulsion to organize artists into groups, I can't tell." Yet it is important to note that only his palette resembled Pop art. His subject matter made no references to pop culture; indeed, it made no overt reference to recognizable objects at all. However, his increasingly monumental works did find inspiration in cartoon illustration, and many critics interpreted the subject matter as more or less covertly sexual—often as vulvar and penetrative.
