The first test batches of the Magic Cube were produced in late 1977 and released in toy shops in Budapest. Magic Cube was held together with interlocking plastic pieces that prevented the puzzle from being easily pulled apart, unlike the magnets in Nichols's design. With Ernő Rubik's permission, businessman Tibor Laczi took a Cube to Germany's Nuremberg Toy Fair in February 1979 in an attempt to popularise it. It was noticed by Seven Towns founder Tom Kremer, and they signed a deal with Ideal Toys in September 1979 to release the Magic Cube worldwide. Ideal wanted at least a recognisable name to trademark; that arrangement put Rubik in the spotlight because the Magic Cube was renamed after its inventor in 1980. thumb|Original Rubik's Cube - Ideal Toy Corp., made in Hungary 1980|leftThe puzzle made its international debut at the toy fairs of London, Paris, Nuremberg, and New York in January and February 1980.
