Dracula's Castle where this image is taken from and sometimes one's mind wanders around. And Halloween is only about three months away. As a child, we used to play "horror" make belief games throughout summer and not only on rainy days. I had not even read Dracula that I was already fascinated by the character. I do remember playing a few Dracula games before "the" Dracula game, but it is very vague in my mind.
I find this drawing interesting in many aspects. I do not know who Dracula is fighting. It could be either Jonathan Harker, who is the "good guy" character played in the gamebook or Abraham Van Helsing, who is the main adversary if the reader decides to play the Count. Van Helsing in the novel is elderly, but in the gamebook he is younger (40s? 50s) and nastier. The odds seem to be even here: the man is heavily armed and has a strong enough built. Of course, Dracula has superhuman strenght, but he might be weakened by the presence of the cross (although the man holds it in a strange way) and the stake is dangerously close to the Count's chest. It reminds me a lot of the climatic combats in the old Hammer movies, especially the one between Peter Cushing (Van Helsing) and Christopher Lee (Dracula) at the end of Horror of Dracula. Tense, dynamic, uncertain, vicious. I wouldn't mind watching some Hammer movies actually.
