Form is Void is a picture blog that I’m not sure how better to describe. Above, from a post of Richard Oelze images. Another post that stood out for me was on Robert John Thornton’s Temple of Flora botanical prints.
Similar picture-heavy and word-light is But Does it Float, where this and other engravings by Albin Brunovsky can be found.
Chaudron is likewise an eye blog. Here’s someting from a post collecting photographs of wind instruments.
Extra - added 7 July 2012:
Ampere’s And: Books and bits.
All My Eyes: Some words as well as pictures, of tennis in Zanzibar, and gunpowder labels, and submarine insignia, and ahh, ugly tomatoes.
Gibbon: A selection of daubers, scratchers, and snappers, snipped and stuck by Limbolo.
Tigerloaf: A very lovely blog by one Dylan Thomas Hayden.
