The LMC old populous clusters are found to be markedly more elliptical than the globular clusters of the Galaxy. The mean ellipticity, averaged for 25 clusters, is 0.22. The distribution of true ellipticities, corrected for projection effects, suggests that very few LMC clusters are spherical, most having true ellipticities in the range 0.2-0.4.
