I wasn't sure what to expect from the lenticular, but was pleasantly surprised. I think the chosen artwork itself has some inherit drawbacks to being used as a lenti, but it does allow for several clearly defined layers. Shaun's bat in particular offers a strong pop out effect. The various silhouettes of the zombie horde in the background extend deeply add great depth.
As for the inherit drawbacks I mentioned, Shaun's white shirt almost seamlessly disappears into Liz's blouse due to them both being so lightly colored. This flattens the layered effect between them, as Shaun should be pretty well defined as the central image of the foreground layer. The predominantly white background of the top 3/5 of the art also creates a challenge for realizing depth, but it's still there nonetheless.
I find judging lentis to be particularly subjective, but I'd rate the upper portion of the lenticular as average, transitioning into excellent as you approach the lower third. I think this bodes well for future lenti editions that have more wholly lenticular-friendly artwork.
The back of the lenti slip features a fair bit of 'bossing around the hand and cracks in the record. Not as impressive as the treatment on the full slip, but solid in its own right.
All in all, I believe EB is on the right track with their products. They are ambitiously designed and fairly priced. I think if they get these logistical issues worked out (and some heavier card stock), they could be right up there with the top premium shops. Hopefully, you all get your copies soon.
