Essential Iron Man Vol. 4 review. Classic Game Room presents a CGR Comics review of ESSENTIAL IRON MAN VOL. 4, a significantly better Essential book with writing by Gerry Conway and pencils by George Tuska, among many others. It collects IRON MAN #39-61, from 1971-1973. As someone that doesn't read too much Iron Man, I can still say this was a fairly interesting book, with one of the few faults being the dialogue, a product of the time, and the limited black-and-white art, a product of the modern Essential Line. CGR Comics Essential Iron Man Vol. 4 features footage of the classic art, albeit in black-and-white, and Iron Man just generally being awesome.
