hmm... hopefully someone can help.
 

I picked this up at a garage sale. Original packaging never been open. I can't find any info on it online. I know it's a Donnie Wahlberg 3 in one cooler, pencil holder, and water bottle, but I don't know if it may be worth something. Can anyone help?

Hmmm i wouldn't call it a toy as much , has it got any company logo's ?

EDIT: found what your looking for hopefully
The Brand name is "NEW kids on the Block" , must be very old TV show or something...

New Kids on The Block Huge Lot Sheets Tapestries Pillow Cups | eBay

i did an ebay world wide search of "new kids on the block"
New Kids on the Block Memorabilia | eBay

looks like they could be worth a bit if sold to the right fan boy or girl, plus i kinda did what you did :P
Hope this has helped
Oh and welcome to toyark

New Kids on the Block are an American Boy Band from the 80's-90's I thought It might be worth something too... just didn't know what that might be thanks for looking!

no problem
