I know we see the logo during the ransom scene in IM1, where Tony is bound, head covered. It's the backdrop of the scene on a red canvas or curtain material. Can't recall if it's anywhere else. A logical place might be in the tents when Stane comes to visit, to steal the Mark 1, but I can't say I recall with certainty.
One would assume that their logo is known(within the MCU prior to IM showing up), has been known, which leads to the theory Killian co-opted it. Gave it a face as he noted.
