Seriously, this happened .... My son has a t-shirt I bought for him last year. He wore it the other day and I noticed around the surfing logo is a very well cleverly hidden skull face. He has had this shirt for a year and when I looked at it before buying it I didn't see it either until two days ago. My husband has a "hawaiian shirt" that also has the skull on it cleverly hidden in its pattern. He wore it several times before I saw the skull in the pattern. He had the shirt a couple years and never noticed it.

Can't be too careful these days as they imbed stuff into what you buy and you never know it.
