Of course it wasn’t a real baby. It’s the shape of the cradle and baby inside the bag. It struck me as being a message that babies can be thrown out with the trash.
I have the ad in front of me (yes, I went and dug it out of the recycle bin to see for myself). In it I see:
a tall white wall with no windows, appears to be painted concrete block
a sign that says “warning: no dumping this site for the square shopping center tenants only violaters will be prosecuted NM (could be HH, hard to tell) C section 7-2.”
A dirt area along the edge of the building, with an area in front of the trashbagged shape–hard to tell if it is paved or hardpacked dirt
a door (not residential) and small enclosed light fixture just above and to the left of the door
gas meter
some weeds along the base of the wall
a shape encased in a white trashbag with red ties
This shape appears to have proportionately large handles that stick out to either side and feet (possibly with wheels) on the bottom, roughly rectangular other than the feet and handles. Top of the shape extends up past the handles (about a quarter of the total height of the rectangle). There is a line that can be slightly seen through the bag extending across the rectangle slightly above the line formed by the handles. The entire rectangle is a little more than half the height of the door and 2 to 2.5 times as wide. Most exterior doors are about 36 inches wide and 6.5 to 7 feet tall, so the shape is about 6 feet long and roughly 4.5 to 5 feet tall based on the comparison.
It bears absolutely no resemblance to the outline of any crib or cradle I have ever seen, aside from appearing to be much larger than any crib I have encountered. There is no other shape, humanoid or otherwise, visible in outline through the trashbag. I see no suggestion of anything other than a retail parking area with what appears to be a retail trash receptacle encased in a plastic bag.
I cannot find an image of it online, nor do I have access to a scanner, or I would let you see it for yourself. If you have already (as is likely) thrown out Sunday’s paper, or never got one in the first place, but want to check out this claim for yourself (as I strongly suggest), your local library likely has a copy of the local Sunday paper. Some bookstores will keep Sunday’s paper for sale throughout the week, and, at least in our area, there are often paperboxes that continue to sell Sunday’s paper through the week until they run out. Do yourself a favor and check it out for yourself before contacting the company.
