If you missed out on backing Andrea Contato’s book on Origin Systems, its history, and its founder, you’re in luck: Through the Moongate is now also being crowdfunded on Indiegogo.

The campaign is being treated as an extension of the Kickstarter campaign; if the total donations from both Indiegogo and Kickstarter exceed €33,333, every backer who opted for a hardcover version of the book will get the gypsy poster add-on as well.

There are only three reward tiers on the Indiegogo page for Through the Moongate at present: €15 will get you an electronic copy of the book, €22 (plus shipping) will get you a paperback copy, and €50 (plus shipping) will get you a hardcover copy.
