Everyone knows that there was a big 3-D craze in the early 1950s. Many of you will also be aware of the fact that comic book publishers hopped aboard the bandwagon by inserting 3-D glasses in certain (higher priced) books. American Comics Group joined the trend in a rather unique way. Rather than go the traditional route, ACG developed TrueVision, a rather innovative way of giving more depth to the comic book page. This house ad gives the reader of a good sense of the TrueVision effect, with the black border and porous panel borders acting as a trompel'oeil. I've only owned a few of these books over the years, but they are really fun and the effect is quite cool. It is, however, a lot of black ink and if the pages are deteriorating at all, you can wind up with black fingertips.
