Recap of the lettering from logofor GAMMA (2010-present), a Dutch hardware store-chain.

Recap of the lettering from Dutch hardware store-chain "GAMMA".

I have absolutely zero clue on who originally designed it.

(If someone here knows more about the origins please let me know, thanks)

Nonetheless it's a pretty cool futuristic looking design as well as a tribute to its predecessors that set the tone for the genre at the start of the last century.

As usual the alphabet is completed and some punctuations is added.
