This 10.0 graded gem is tied for the FINEST QUALITY CGC example of this issue to appear at public auction! Talk about unique! Two original Grande cards joined together with perforations between them. A museum collectible in museum quality condition of John Mayall and Big Brother & The Holding Company!


The experienced collectors we talk to are 100% convinced that posters that have somehow miraculously earned a 10.0 grade from CGC are exceedingly undervalued at current market levels. Their reasoning is simple but firmly grounded in reality. In every other certified collectibles marketplace it’s COMMONPLACE for the absolute “Best of the Best” to command premiums of 10x 20x or even 50x the next grade down. These types of premiums are universal and longstanding in regards to the values of rare coins comic books baseball cards paper money postage stamps etc.


Because independent authentication and grading of concert posters is still in it’s early days premiums have not yet approached these types of levels. But make no mistake premiums ARE growing as collectors from other fields are flowing into the marketplace and snapping up what they consider to be MASSIVE bargains. We first discussed this opportunity in our blog dated 8/19/16 and recently updated it on 6/18/18. We highly recommend you read each blog carefully if you are interested in participating in this exciting segment of the marketplace. 


The Grande Ballroom series produced some of the finest imagery from the 1960’s music scene. In many cases promoter Russ Gibb chose to only produce postcards to promote events. That being the case Grande cards and card sets have become one of the most highly sought after items by serious collectors.
