As a student, Beshkov published caricatures in the "Maskarad", "Div Dyado", "Balgaran", "Starshel" and "Vik" magazines and illustrated the issues of the T. F. Chipev and Hemus printing houses. From 1925 on, he co-operated with the "Pladne" magazine among others. He was twice arrested due to his leftist political views: once after participating in the June Uprising following the Bulgarian coup d'état of 1923 and then during the 1925 April Events in the wake of the St Nedelya Church assault.
