They look like Original Style; go to better tile showroom in the area and they should be able to help you.

Here you go: Restoration Tile

Or Tile-Source--weird website though.

all of that can be done with 2x2 tiles, and 3x6, cut to size. it's a boat load of work to lay out that floor. the tile is the least of your worries, as you will need a tile artist to get that pattern to look like that.

looks like your standard ceramic tile in a matte finish. retro renovation will have those colors.
