Andy Park, the series' original artist, made the official announcement during the SDCC panel "20 Years of Tomb Raider: Lara Croft's Multimedia Empire." The book will include a foreword by Park and feature his artwork, as well as the work of renowned comic artists Michael Turner, Marc Silvestri, David Finch, and many more. Writers include Turner, Dan Jurgens, and others. The set will be published by Dark Horse, which produces the current Tomb Raider and Lara Croft comic series.
Here's a breakdown of the four volumes:
Tomb Raider Archives Vol. 1: Issues #1-15
Tomb Raider Archives Vol. 2: Issues #16-24, #26-34
Tomb Raider Archives Vol. 3: Issues #35-50, #0, #½
Tomb Raider Archives Vol. 4: Tomb Raider Journeys #1-12, one-shots
Volume 1 will go on sale November 30, 2016. It will have 408 pages in an 8" x 12" hardcover format. Volumes 2 through 4 will follow next year.
Apparently issue #25, "Endgame," a Tomb Raider–Witchblade crossover, could not be included for legal reasons. That's unfortunate, but if you simply must know what happened, copies of this issue can usually be found at reasonable prices on Amazon and eBay.
