I don't have many good ones to start off with.

Looking for getting a collection going to showcase the days of tomorrow, as was seen in the past.

Not really a cyberpunk or dystopian future, but one full of new designs, new technology, the space race having put stuff up in L3/4/5 orbit, just things that never happened.

50's and 60's scifi art sort of, but also cars, fashion, architecture. Anything that fits the theme
