Model by DeAgostini.
This model appears in at least two other Atlas collections: a red/white version like this one, but with white side 'flashes' instead of the "Mavaut"-logo in a collection of buses from "iron curtain"-countries, and a similar one, but blue/white, appears in a Ikarus bus collection, meant primarily for the Hungarian markets.
Please note, that the two other versions have the launch year for the bus stated as 1960, not 1959.
