What is claimed is new and desired to be protected by Letters Patent is set forth in the appended claims: 1. A cooler having spaced apart walls forming a compartment in communication with a base and a lid wherein said walls and said lid are comprised of transparent planar elements, wherein said base includes: T-rails depending from a top surface of said on opposing sides thereof, said T-rails are substantially parallel to each other and extend substantially the length of said base; and apertures extending through said base positioned on sides adjacent to said T-rails, said apertures forming receptacles for receiving locking elements having springs for extending and retracting said locking elements and said locking elements can be extended or retracted to engage T-channels longitudinally extending along opposing ends of the base, and wherein said depending T-rails are capable of slidably engaging longitudinally extending T-channels positioned on a bottom edge of opposing sides of said cooler, said slidably engaging T-rails and T-channels are on adjacent sides to said locking elements whereby when said locking elements are engaged the slidably engaging elements are fixedly positioned. 2. The cooler as recited in claim 1, wherein said lid has a peripherally positioned flange having a top surface and an interior surface whereby said flange engages the walls of said cooler. 3. The cooler as recited in claim 1, wherein each of said walls are formed of at least two transparent planar sheets, said transparent planar sheets having a common base wherein said transparent planar sheets are spaced apart and are substantially parallel. 4. The cooler as recited in claim 3, wherein said common base of at least two of said transparent planar sheets have a T-shaped channel extending longitudinally therealong. 5. The cooler as recited in claim 4, wherein each of said walls have an edge extending perpendicular to said common base wherein said edge has a T-rail extending therealong. 6. The cooler as recited in claim 5, wherein said spaced apart walls have an interiorly positioned T-shaped channel extending vertically on the opposing end of said T-shaped rail. 7. The cooler as recited in claim 6, wherein said T-shaped rail of each wall mates with a respective T-shaped channel of an adjacent wall in order to form the exterior walls of said cooler. 8. The cooler as recited in claim 7, wherein one of the transparent planar sheets of each wall forms an exterior side of the cooler wherein said base and top edge are in communication with said exterior side. 9. The cooler as recited in claim 8, wherein said exterior side has an aperture on the opposing ends whereby a placard of substantially similar dimensions can be inserted therein. 10. The cooler as recited in claim 9, wherein said aperture extends between the top edge and base of said wall. 11. The cooler has recited in claim 3, wherein said spaced apart walls are open on a top edge thereof. 12. The cooler has recited in claim 11, wherein one of said transparent planar sheets forms an exterior wall of the cooler and another of said transparent sheets of each wall forms an interior wall of the cooler, and further comprising a first flange extending along an exterior surface of the exterior wall and a second flange extending along an interior surface of the interior wall. 13. The cooler as recited in claim 12, further comprising a cap for covering the opening of said top edge. 14. The cooler as recited in claim 13, wherein said cap has opposing flanges extending the length of the cap. 15. The cooler as recited in claim 14, wherein said opposing flanges of said cap each operatively engage a respective one of the flanges on said exterior and interior walls. 16. The cooler as recited in claim 15, wherein said cap has a plurality of gasket-like elements in engagement with the adjacent gasket-like element are parallel with said flanges. 17. The cooler as recited in claim 16, wherein said plurality of gasket-like elements of said cap are in engagement with the top open edge of said walls forming sealing means for said open space.
