Three unattached cardboard sales panels advertising that "over 25,000,000 pieces of Pyrex [are] in use". Panels, at one time, were affixed to one another. Panel originally on left, titled "For tea", features image of transparent Pyrex teapot with saucer and sugar dish. Text featured below. Panel originally on right, titled "For gifts", features image of couple examining transparent Pyrex cookware and tableware. The woman, dressed in pink, is holding a covered baker. Text featured below. Panel originally in center, titled "Pyrex", features brief text: "over 25,000,000 pieces of Pyrex in use. No home can have too much Pyrex". This panel allowed for various inserts to replace text, as described on verso; four metal fasteners can be temporarily removed to secure inserts.
Some minor staining and puncture marks on versos.
These panels arrived with a 1925 Pyrex advertisement, see Bib 123578.
