This is an unknown Pyrex pattern that appears on standard size mixing bowls. We’ve seen them occasionally sold together at swap meets, but have not seen an original box yet. So, it’s unknown how it was originally marketed.
In fact, it’s still unknown if this was in fact a promotional item(s) or not - the bottom of the bowl is quite mysterious because there are no markings to speak of on the one we have. Others have noted that it occasionally has a small batch number. But to date, we haven’t heard of anyone who found the usual Pyrex markings on the bottom.
Because of this, it has been speculated that the bowls may have been made for a third party product, or perhaps they are older (as some of the Primary Mixing Bowls which have no markings on the bottom). We tend to think that they aren’t as old, but aren’t sure.
The shape of the bowls look exactly like the standard 400 series of mixing bowls. We’ve compared ours (which is a 403 2.5 quart shape) to another Pyrex mixing bowl and the shape is identical.
The pattern has been called many things, but one consistent name that seems to have stuck is “Eyes” so we’ll stick with that for now. The pattern is a turquoise color and features vertical oval shapes with a cross in the middle.
Update 04/2009: For awhile now, we’ve been hearing reports of collectors finding the “Eyes” Pyrex bowls with actual markings on the bottom. This is great to hear as it confirms that these were indeed made by Corning. Collectors report the standard sort of Pyrex markings on the bottom of the bowls (i.e. 403 2 1/2 Qt). It’s still unclear the origins of these bowls - whether they were a promo or made by a third party.
Update 04/2012: Thanks to Laura of forgetmenotsonmemorylane, the mystery of the “Eyes” has been solved. It’s actually called Hot ‘N’ Cold Chip and Dip set. See this post for photos and more!
