I've always liked Frank Howard's 1962 Topps card, with his TGP or TG12. That glove looks big even on him, and the card says he was 6' 7" and 225 pounds. I found a couple other photo's of him with Macgregor gloves, too.
My first summer job was on the janitorial crew at Milwaukee Co. Stadium in 1970, when I was 16. If we had to come in early to finish cleaning the stands before a day game, they'd let us stay to watch the game. I got to see Frank playing left field for the Senators and Ted Williams, who managed them, standing outside the visitor's dugout. Frank looked big even way out in left field. He had a great year in 1970 and led in HR's with 44, and also led in RBI's and walks.
