Of which edition of WrestleMania is this the logo ?

yup, it was WrestleMania's edgy teenage years

(There's only one of the classic logo where the number is below the name WrestleMania. All others are behind or right next to it.)

Subtitled "the first WrestleMania under the sun" , WrestleMania XXIV was the very first event held in Florida, and the only one of them to have had a number in its logo.

It's the only WrestleMania logo to have ever reused the classical original WrestleMania font after WrestleMania XV

"Can we get Ric Flair an escalator ?"

the first logo to stray off the classical WrestleMania font

It was implied that a version of this logo was planned for WrestleMania IX, but got replaced as the Caesar's Palace venue was confirmed.

There are two like these, I know... but the left grooves on the numeral shall help you

One of the worst WrestleMania of all time, despite an inspiring logo and a wonderful stage

Heat !

One of the best, if not THE Best WrestleMania of all time.

subtitled DX-raided, this logo was the very first one to not feature the number at all. Something that would not happen again... until WrestleMania 31, a.k.a. YouTubeMania

albeit similar with WrestleMania 38's logo, this is WrestleMania 25's logo, which might have been an inspiration.

Considered as the last WrestleMania of the Golden Era, it saw the first Ladder Match of 'Mania history, the great Hart vs. Hart match, and the WWE retirement of Macho Man Randy Savage.

Yup. I struggled, as you can see, to remove the whole golden XV from the rest of the logo

(use the remaining parts of the numeral behind the word "Wrestle" to figure out)

also was the first-ever WWE WrestleMania (previouses were WWF WrestleMania), and the first one to include the brand separation between Raw & SmackDown.

Considered by CageMatch.com to be the second best WrestleMania of all time, after X-Seven.

Yup : It's the next one coming. Let's hope it's gonna be better than the last one...

Considered by many as the last good one, WrestleMania XL saw the powerful climax of Rhodes failing to defeat the Rock, then successfully take the title from Reigns the very next day. 

the one that went Hollywood, and saw the very first Money in the Bank Ladder Match.

Can you guess the correct edition of WWE WrestleMania from its de-numbered logo ?
