Description

Mickey Mantle Powerized MM4 GENUINE LOUISVILLE SLUGGER Hillerich & Bradsby baseball bat
I believe this may be from 1960s?  If you know more (which is likely) feel free to fill me in.  Thanks.  Great to display.
Vintage baseball bat, nice clean and strong debossed black logos, I am not expert in this field as I buy all cool things (and this is a cool thing!), so I try to learn and photo and explain all details I find.  There is a tight slightly visible crack (see detail photos) that follows the grain in the handle of the bat - it doesn't feel deep and nothing is missing but you can feel the small edge - and the point of that grain crack is about 10 1/2" from the bottom and is 3" or so on each side.  The bat is super solid and has a good solid ring to it (when I tap on my tile) so structurally seems good.  This has a some various age and use wear with some rubs and nicks and stains etc. which may clean but I am not sure how to do that so leave it to you.    Total length if 34" and it weighs 1 lb 12.5 ounces.  See detail photos.
See title, description, and detail photos.
See title, description, and photos and let me know if any questions.  Thanks.  Stay healthy and best to you during these times.
Keep checking my auctions as I will continue to put on nice coffee cans, beer cans, and tins!

I try to ship at reasonable cost so for some large items that may mean using fedex post and taking a week but I mostly use USPS first class/priority depending on value/weight.  I use good packing materials and take care of items as I am a collector first and know how I want to receive my items
All items are sold as-is as found. Returns will only be accepted if we have grossly misrepresented the item in the description.  So far this has worked out well as I sell many kinds of hard to find items and most of you know what you are looking for and will ask questions in advance and bid appropriately.  So far no negative feedback so I will do my best to continue that.  :)
