Both look like the second printing.

To see examples of the first printing, go to the StampStore at
stamps.org.

"United Nations Philately" edited by Arleigh Gaines:
"The shading under the word "Unies" on the 8c denomination was
corrected between printings. On the first printing, there is a white
gap under the first leg of the "n". On the second printing, this has
been filled in. The lighter shading lines on the background of the 3c
denomination also have been strengthened."
