About the Shadowless printing

Which object this page prices — and how to tell it from the standard Impostor Professor Oak.

The Shadowless Impostor Professor Oak is from the print run between 1st Edition and unlimited: no drop shadow to the right of the picture frame, thinner HP type. Fewer were printed than unlimited, and the market treats it as its own card.

How to tell · right-hand edge of the illustration window

On the WOTC printings (1999–2002): no drop shadow down the right side of the picture frame, thinner HP text, and lighter colour. Every 1st Edition Base card is also shadowless — the stamp is what separates the two.
