Rubik's Cube Politoys Trial
In March 3, 1975 Erno Rubik gave the cube to Politechnika (later politoys).
In 1977 Politoys started the manufacturing (first time) of the Rubik’s cube and the make 12000 pieces of it for local businesses to Hungary.
Since the cube was worthless and nobody actually cared about it (they sold a few hundred pieces) an other company came in named TRIAL with a different marketing strategy. We are still in 1977. TRIAL company took approx 11000 pieces from politoys and painted their logo TRIAL on the white side of the cube. TRIAL failed and couldn’t sell.
In 1979 September 17 a IDEAL Toy company signed a deal with Erno Rubik and took all the cube from TRIAL (these are the cubes that were taken from Politoys).
In April 1980 Politoys started manufacturing the cube’s with the plastic casing etc... Politoys also took the inventory of IDEAL.
The bottom line: This is one of the first original Rubik’s cube because it has the logo of three different companies. Politoys, Ideal and Trial.
It says 1981 but it is definitely from 1977. What I wrote down here is what I heard from an old man working at Rubik Studios and he also worked for TRIAL.
