Transparent spell effect grids

[Oryan77]

I recently got ahold of some 8 1/2 x 11 transparent sheets that have printed images of spell effects like Darkness, Fireball, Glitterdust, ect. They have grids printed on them to show the area of effect. Does anyone know where these originally came from? They have the D&D logo at the top. These things are fantastic and I'm wondering if there are more versions and larger area sheets?

I believe that they come from the retail packs Wizards sends to game stores.

You can get these from the RPGA tournaments.

Or try searching for "RPGA" on eBay.

The guys in my group just make them with photoshop.

The RPGA's distributed them in several venues. I've got several that I've gotten through my membership in the RPGA's GM Rewards program. I believe they've sent out the same (or similar) ones in the Retailer Packs.
