In a definite first, TD Ameritrade and Havas have placed an ad in the blockchain as a celebration of innovation and creativity.

The ad is made up of 68 Bitcoin transactions, each containing of a string of 80 computer characters that come together to create ASCII art. It can only be viewed visually on a landing page. When it all comes together, the transactions form an image of a flag being held by a hand and featuring the TD Ameritrade logo.

The goal was to demystify finance, cryptocurrency and the blockchain. While putting the ad together the team had to consider that since each string is limited to only 80 characters, they had to be clever in character use, and chose only Unicode characters or simple typewriter characters (slashes, equal signs) to create the design. The first transaction contains an initial line, “See the full picture at” They then built the rest of the design from 67 additional transactions.

Each transaction contains a single line of the ASCII art, which, when taken in totality forms the larger image of a flag.

The ad was meant to spread word of mouth in the finance industry and across social media.
