EF International Language Centers typographic logotypes for their 40 destinations, worldwide. I like the unity of these logotypes, how they're all simplistic yet each of them still have their own style about it which makes them somewhat unique.
I really logo this logo. The mountains connect that this company is meant for the outdoors. The dotted line with the X also connects it has something to do with travel as well. The font is very sleek and compliments the logo well.
