Created in 1993, Altaya Editions (Planeta DeAgostini) is a maker of publications and collectibles. During that time, it has launched over 360 items in 10 languages and 22 countries.
In 1999, Altaya became part of Group DeAgostini Planet, maker of the DeAgostini range of 1:43 scale military vehicles. Altaya has also been marketing partnerships with firms such as: Scalextric, Bycmo, IXO, PCT, Frontline Figures, and Games Workshop.
In 2005, Altaya started series of 1/72 military vehicles (mostly tanks). These are fair to good quality, depending upon the vehicle. Some are more toy like, others are more of a collector grade. The main weakness is a lack of "crispness" to items such as hatchlines, tools and cables. The paint schemes can be a bit odd as well. The positive is the sheer number of "obscure" vehicles being manufactured. Let's face it, it is hard to find a LeClerc, Cromwell, or Souma S35 in 1/72 diecast.
Each vehicle comes with a small 8 1/2"x11" booklet on tanks. The beginning and end are a bit generic. The middle portion deals specifically with the associated model.
