This is what I did:
These are some lettering that i found in the street:
MU: is a simple lettering, but the letters are connected and the exclamation mark makes a really good connection with clients.
MARITXALAR: This is a jewellery shop, and they use a delicate lettering because they want clients to think that their jewellery is very delicate.
GARAZI: they use basque lettering, because it is an old store and as their clients are basque, they want to attract them.
