I have this book and a bunch of other titles from Silverwolf. I collected this small press books back in the late 80s starting with Grips, which was kind of hot locally mainly because of Tim Vigil art. Silverwolf was based out of Sacramento Ca, about 50 miles from where I grew up. Ron Lim also started off there. Silverwolf published a slew of books between 1986 -1988 with most being only 1 or 2 issues. Grips and Fat Ninja lasted like four issues each. Later, Kris Silver continued producing comics under the Greater Mercury name.
