New examples of genus 0 and 1 are described and the classification of complete improper affine maps with at most two embedded ends will be given.Mathematics Subject Classification (2000): 53A15, 53A35Research partially supported by MCYT-FEDER Grant No. BFM2001-3318 and Junta de Andalucía CEC: FQM0804.
