Cute pony, can't say I know what it's from, though. I can say that you captured the style you were (partly) aiming for quite well. I always adored those old Air France posters and ads. In fact, I used to have a decent-sized collection of them. Wish it could have gotten bigger, but what hindered it (at first) was both simply the rather high prices many were being sold for (I always liked to think that when I became a captain I'd be able to purchase a lot more of them. As much as I loved my job, being a FO for AF brought in a less than most would probably imagine...) and also because my wife started to get upset at how much wall spaced was being used up from me framing and hanging the things just about everywhere I could. I told her that I was sorry, but a majority of them were just too pretty or cool (lots of times even both) to have stored away. She just groaned and started taking some down.
And then I was forced to stop collecting them for good shortly after that... (ᶰᵒ, ᶰᵒᵗ ᵍᵒᶦᶰᵍ ᵗʰᵉʳᵉ)
Of course, I was forced to stop a lot of things then.
