Display sign frames in black, pumpkin orange or purple. They will hold a card stock or paper sign of about 9" x 19" and up to 1/4" thick. Each has a 1" wide frame with a 3/4" "mat". The mat is cleverly designed as a snap hinge which opens to allow you to replace the paper sign and snaps shut to hold it firmly in place. Construction looks like some kind of fiberboard with a plasticized covering. (2) 5/8" channel hangers on the back will fit over the spine of standard gondola shelving.

So the poster is really brand new. The animals on it are (1) to (190) million years old, and if that doesn't qualify as pre-history, may we stumble over a glyptodon in the dark. Invicta Plastics Ltd. of Leicester, England, printed this 23" x 16-1/2" poster with a colorful diorama to promote their authentic scale models of prehistoric animals. A time line across the bottom lists dates and data for a dozen of them, from the plesiosaur to the woolly mammoth, and compares their sizes to that of a pair of five-year-old children. Post it on the fridge to spark supper discussions, or in the classroom as a source of extra-credit questions for science quizzes.

Neon strip cardboard spectacles with diffraction gratings as the lenses. You can see the regular world, but all light sources and bright objects appear in multiple rainbow hued images. The effect is a little as though the whole world were a giant hologram. Great stocking stuffer or birthday party item for grade school ages.

This idea is for the birds. Literally. A green/black plastic perch, dish, and dispenser that you can screw onto an inverted plastic pop bottle to convert it into a bird feeder. Obviously, the bottle should have been emptied of pop and filled with seed. One of those "100 things to do with old coat hangers" ideas that really works!! Complete with instructions and bail to hang the completed feeder. Please note: this feeder will not attach properly to the new Coca-Cola low-profile bottles.

Microscope on a keychain unlocks the secrets of the very small, and of your house, car, tool box, or sample kit. Whatever you have locked with the keys on the key chain! The microscope is actually a plastic magnifier, 5/8" dia x 1-1/2" long OA and is of surprisingly good quality!! The packaging says it is 20X but we estimate it is in the 10X to 20X range. The key chain snaps on with a 2" long chain and has a circle holder for keys. It could double as a belt clip for the magnifier. Durable, great for kids, camping and general knock about service.
