Am looking for the font for the OUIJA logo itself. Not the lettering on the board I know that is Captain Howdy but I want to find the slab serif they use or close enough too.

Thanks!

It's actually the same font that's used on the ABCDEF... letters. The closest match is Captain Howdy.

What the artist did was remove the curled serifs and made them flat.

Then, the easiest way to reproduce that font is to:

1) Type the word OUIJA in the Captain Howdy font.
2) Then make a clipping path in Photoshop.
3) Go to EDIT ---> TRANSFORM PATH ---> WARP PATH
4) Choose ARCH and then choose the bend to 40 and it will reproduce it perfectly.

It's similar to a font called Claredon.
