 His prowess as a draughtsman was evident in all he did and can be seen clearly, for example, in an early "Self-portrait" (Ulster Museum), done in pencil in about 1927.Here his sense of purpose is complete, his 'line' precise, taut and economical; qualities which can be seen, too, in another "Self-portrait" of the same time, but done in oils (Ulster Museum).This concern for line is evident also in "The Lustre Jug", 1934, where he has also taken delight in conveying the surface qualities of the various items in the composition.
