The pieces were commissioned by The Outside Collective for Texas Instruments in a 'Where's Wally?' style, with Jack Kirby; one of TI’s most revolutionary employees hidden in every illustration.

To celebrate 50 years since the invention of the microprocessor on Jack Kilby Day, Texas Instruments launched this campaign which outlined 'Jack’s Journey' through the past half century, and beyond. The four images were shared on Facebook and other social channels and users were challenged to 'Find Jack'. Jack Kilby wore horn rimmed glasses, can you spot him in these fun and colourful illustrations?
