We present lightcurves, shapes, and 3D convex spin-axis models for two main-belt asteroids: (3657) Ermolova and (5325) Silver. The photometric data were obtained at the Skalnaté Pleso Observatory (High Tatras, Slovakia) only. The models were obtained with the lightcurve inversion process using combined dense photometric data from the apparitions in 2006, 2010, and 2013 for Ermolova and in 2006, 2010, and 2013 for Silver. The analysis of the resulting data found sidereal periods and possible ecliptic pole solutions (J2000.0). Currently, only 1592 models are known for 907 asteroids. Knowledge of individual asteroid shapes and spin axes is vital for the understanding the Solar System.
