pro sports memorabilia, baseball memorabilia

One of my favorite pizza places back home has their pro sports memorabilia displayed proudly on their wall. One of the local villagers has taken to framing various memorabilia, such as trading cards, photographs, autographs, and more. Their work is incredible, and it is displayed proudly by my friends, the pizza place owners.
These framed pieces are from various sports. They feature baseball memorabilia, football memorabilia, and even NASCAR memorabilia. I have always wondered if the designer of these plaques stood in long lines to get the autographs for these plaques, or if they are replicas.
Other things that I have seen displayed on people's walls are jerseys, caps, and pennants. My grandfather is an avid fan of pro baseball. He collects baseball caps. He must have at least 10 of them! He has gotten them from attending ball games, as Christmas gifts, birthday gifts, Father's Day gifts, and more. I have considered getting him one of those plaques for his 85th birthday this year. I guess it's time to do some online shopping! Maybe I can get one for a discount!
