The 10 μm bar is 59 pixels long, with the last pixel gray, so 10 μm is between 58 and 59 pixels. I used 10 μm = 58.5 pxl, which converts to 1 mm = 5850 pxl.
The height of the tower is about 655 pxl (using a midpoint between the front and back feet). Converting this to mm: 655 ÷ 5850 = 0.112 mm or about 1/9 mm.
The angle of the photo may have shortened the apparent height (very slightly), and my scale might have been off by 1 percent, but the numbers above should give you a good idea.

P.S.
lamarzocco,
Your 100-150 μm is reasonable, but this is 1/10-3/20 mm, not 1/10-1/15 mm.
