The Steam Summer Sale may be launching soon, the appearance of a set of new “mysterious” cards on the Steam Marketplace suggests.
As spotted by Steam Database, the new set of cards currently lacks images, similar to another mysterious set of cards which surfaced around the same time last year. A week later, those cards were revealed to be part of the Steam Summer Sale for 2013.
While these new cards give no indication as to when the sale will launch, they do suggest that Valve is getting ready. Historically, the Steam Summer Sale has launched on a Thursday towards the end of June or the start of July.
