Apple appears to have confirmed the launch date of its long-awaited iPhone 7
The event is taking place at the Bill Graham Civic Auditorium in San Francisco on Wednesday, September 7, at 10am local time, (6pm BST).
Apple often likes to include a hidden message in its invitations, but this one gives very little away.
It also features a number of translucent coloured dots outlining the top portion of Apple's logo, which may relate to the rumour that Apple is planning to introduce new coloured handsets.
In photography, this out-of-focus effect is called bokeh. It is usually hard to create with a phone camera, suggesting that the iPhone 7 could feature an upgraded camera lens.
However, these dots could also be water droplets, which would be relevant if Apple was planning to launch a waterproof iPhone.

The most persistent (and controversial) rumour is that Apple is going to get rid of the headphone socket.
This means you will either have to buy a pair of headphones that use a Lightning cable, get an adapter, or use Bluetooth headphones.

The rumour is that it the larger iPhone will get a dual-lens camera that will be able to snap SLR-quality photos and 3D images.
There has been a lot of talk about Apple removing the Home button, but the latest rumours suggest this will be a key feature of next year's model.
Instead, Apple could add some pressure-sensitivity to the Home button, meaning it will perform different functions depending on how hard you press it.
These lines currently allow radio signals to pass through the metal casing and reach the antennas. However, it looks like Apple may be planning to redesign the case to get around this restriction.
