We present first Doppler images for the two rapidly rotating, single
K-giants HD 109703 and HD 217352.  Optical spectroscopy and photometry
are used to determine the fundamental properties of the two systems.
Both stars appear to have higher than normal lithium abundance,
non-LTE log n of 2.37 (HD109703) and 2.40  (HD217352), and are located
at the end of the first Li dredge-up on the RGB.  Photometric
observations reveal rotational modulation with a period of 13.89 days
(HD109703) and 17.94 days (HD217352).  Also, signs of significant
chromospheric activity are seen in the H alpha line of HD 109703.
