Not Brown or Circular, by Lineto.

I'm sure we've discussed this double-story g with the square ear before, but I can't remember its name....

Heyman, is this from a print publication, or museum signage?

The more details you can provide, the better we can narrow down the foundry.

Productus from Font Bureau has a similar g and i, but isn't right for the rest of the alphabet....

Kevin, thank you so much for your question.
It's a publication from Unseen. This is the website:
http://www.unseenamsterdam.com/tags/magazine

I notice the same font is used on the website and I simply used the browsers 'inspect element' to find the font
Apercu Bold

Ow and all the others, thanks for your efforts, it's really appreciated!

FOUND IT

Apercu, by Colophon:

How dit you found it so fast not even knowing the website, and the source of the publication?

I knew it had to be one of the new, "trendy" sans serifs, and if it wasn't Lineto's Brown or Circular, I could still find it here:

Thank goodness its name started with an "a"....

haha, well thank you for your help!
And that website is one to bookmark!
Cheers Heyman
