The Big 8 was more a mid priced model and not professional grade. I think originally in the $20 range versus $40 for HOH quality. The glove is a popular collectible especially with the picture box. I have tried to buy the glove only on ebay and the price seems to be $75-$120 for a nice example. It's a cool looking glove with the X-web. It can be hard to find but shows up occasionally on ebay.
Another rare model is this Nokona glove from 1951. The two piece face harkens back to the early days when inventors were experimenting with creating deeper pockets for gloves and mitts. Nokona made the standard issue laced pre-formed pocket gloves and this two piece face "Bob Lemon" G54 model was touted as having the deepest pocket of them all. The seam across the pocket was also used to keep the heel padding secure. The "Bob Lemon" G54 and "Don Hoak" G53 models were made for 5-6 years in the early 50's. I don't recall any models surfacing yet with that particular feature.
