I have been scouring Ebay for playing cards for 15 years - I have only seen this deck of Silver Spur playing cards once before... However the cards inside are plain cards - no logo. I messaged the person that has this auction and he confirmed that the cards are plain inside. So you would be collecting this one for the box only. Since I collect logo'd backs this does not interest me, however some collector may find the price right on this.
