Great Smoky Mountains 10 cent United States Postage Stamps Sheet of 50 Yellowed

This Sheet of stamps is in good condition. Maybe from the gum bleeding through? This sheet is plate number 21342. They show normal wear from age/being handled. There is some heavy yellowing/discoloration.

Look at all pictures to see the condition. I will be listing more stamps so be sure to check out my other auctions.
