A free monthly magazine included in Mail Orders and in White Dwarf subscriptions. It mainly promoted the current month's releases, but also carried some conversions and other modelling articles. It ran from Issue 1 (UK November 1997, US January 1988) for 80 something issues.
The UK and US editions have similar but slightly different content or layout, but the price comparisons can be interesting. Given that the US release schedule was a couple of months behind the UK, the stagger between issues is about right.
