some comments :
#1 and #68 : interesting work on the font, but unfortunately not related to art exhibitions
#12 : strong idea but this logo uses capital letters, is not made for a website, and is too square
#14 : the font is better than in #12, smoother, but not bold enough. The sign is too close to the fedex arrow
#19, #20, #60 and #61 : interesting work on the two first letters (e and x) but not related to art exhibitions
#69 and #70: good attempt to express the “naute” part of the word but what really need to be expressed is “expo” (art exhibition). #70 has a good energy.
#62 : too masculine
#65 and #66 : too classic, underlined, not related to art exhibitions
#49 : interesting idea (paint lines for X) but too kiddy, we’re not keen on this kind of colour too
#74 and #75 : too institutional and fonts should be less common
#59 : too serious (looks like an airlines company)
#71 : more fantasy in the sign, but the sign should be integrated in the word “exponaute”, and the font is too square
We hope it will be helpful !
