Danny Trejo! Did not expect this one to work when I saw that you could request via email as I thought for sure he would be inundated with requests. I was extremely surprised to receive this a few months later with the specific request of the Star Wars Book of Boba Fett Poster!

I’ve recently seen that he’s is no longer accepting email requests, and I’ve updated my site to reflect that information. When you write to him be sure to send him a self addressed 9 x 12 stamped envelope with your request.

Knuckleball.app is completely free and a great tool for keeping track of who you send to, returns and failures as well as behaviors with a tagging system. We’re different than SCF and Startiger.

Boomer Esiason! There is something about a card you’ve had since you were a kid getting signed. Bengals are my hometown team even though I no longer live in Cincy. There are two addresses floating around and this one took quite a long time, but I went with his official foundation’s address and confirmed it directly with them before including it on my site (both will work however). I’ve included the address and fee info below.

That experience is exactly why I built knuckleball.app. It’s newer, more user friendly, and won’t inundate you with ads or make you time travel back to web surfing in 2007. It also has features like tags that help collectors understand player signing habits over time.

Wade Boggs via Knuckleball.app

Wade Boggs is a name from my childhood, and I’ve cherished this card since then! It was even more special to send it with my son for Mr. Boggs to sign, now my son can enjoy it too. Seeing his signature on this iconic 1990 Score All-Star Team American League card is amazing, and the illustration captures the essence of the ’90s perfectly.

All details, including address and fees, are available on Knuckleball.

This Donruss Diamond Kings auto was my first one, and now I'm completely hooked! I also picked up a box set of the '92 Donruss cards from my local shop and sent that. Junk Wax is TTM gold! The addresses, success rates, and fees are all right there on Knuckleball.
