Passing along an offer for Black Art Graphics. They produce custom (to your car, your specs), aluminum, auto-related plagues and are offering a 20%-off group-buy discount, in effect as they already received their minimum number of commitments.
These are blueprint-style technical illustrations laser-engraved into 3mm-thick double-finished brushed and anodized aluminum (aluminium, I should say -- they're produced in the UK).
The discount is in effect through May 7, 2018 and the code is: "LOTUSTALK20".
I'm getting one of these made, complete with customizations. I received one proof back so far with my custom rear panel, above-the-diffuser exhaust, front splitter and sector diffuser and it's looking really nice so far. I stumbled upon them back in I think 2016 and, back then, the Lotus artwork had a "coming soon" banner over it. Forgot about it until the recent group buy posting.
