1967 Korea Turtle Ship Stamp ID Please!

Can someone here please help me ID the Scott Catalog # with more information on the 1967 Korean stamp? I'm unable to find any from an online stamp catalog or sales venues. Does anyone also know the denomination? There's none shown on the stamp itself. Anyway, we have a block of 4 of this, and it's the original from 1967, but there's absolutely no information from what I can find online.

The only picture of the stamp that I found online was of a (reissue?) in 2013 of Korea's 10 best stamps over the years (the bottom left one):

Thanks in advance!

These look like Christmas seals, rather than postage stamps.

It says right on the sheet "Christmas seals". And what is a turtle ship?

We have the one that's from 1967, the original one. This Christmas seal looks to be a remake of the one in 1967. Were they simply Christmas Seals from 1967?

A turtle ship is the first ironclad ship in the world.

These 10 christmas seals are the top ten best starting with the first seal produced in 1953 representing the 60th anniversary in 2013. So with your seal there is a 1967 version and a 2013 version.
