From Carpe Diem:
This post has become an annual tradition at CD around April 15.
Page 1 of the original IRS 1040 income tax form from 1913 appears above. There were only four pages in the original 1040 form, including two pages of worksheets, the actual 1040 form above, and only one page of instructions, view all four pages here.
In contrast, just the current 1040 instructions, without any forms, runs 189 pages.
