Closed Zone Passes.

[CtahhR]

Here is a pair of Passes "With the right to enter the closed zone" to Ministry Of Auto-Transport worker Vjacheslav Stepanovich Kovalenko, valid until 10th December 1986.

The white pass is for "F-1" #017129, "Everywhere".
The green pass is for "F-2" #012737, "Chernobyl'".

No doubt as an Auto-Transport worker Kovalenko will have ferried people or logistics into and out of the "Exclusion Zone". They come laminated with two holes punched above the top of the pass, so these were most likely worn round the neck.
