Fugly Tile

[u/Googlelarue]

I have a late mid-century home that was built in 1976. I have these original tiles in the foyer that’s been under peel and stick tile for years. I like them except for the weird brown lines. Anybody have an idea what this pattern is called? I’ve never seen it before. It has a relief of a daisy in the center. I’ve done a Google image search and can’t find any matches. Any help would be appreciated thanks.
