Bonjour!
Welcome to the site. I'm happy to see newcomers here, your work looks good.
As you can see, there's many restoration levels here, from the ones like yours which try to respect and preserve the original scan, to the ones which try to recreate the original vectorized design.
Feel comfortable doing your own research and let me know if you want anything about restoration, or if you need logos, fonts, etc. I'm more on the recreation side than the preservation side.
