J is also for Jack-O'-Lanterns, the first ever USPS Halloween stamps issued in 2017. Halloween is huge in the US, so I am surprised that they don't have issues every year. They were certainly a success, as they are no longer available from the online store, unless you want to buy giant press sheets for $60 dollars each (I think that is 120 stamps). A few post offices might still have them in stock.
I received one as part of this months envelope exchange run by Jean W over at Pushing the Envelopes - this one is the fantastic handiwork of Chuck M. I love how the close-up photo came out - it really shows off the inner glow of the pumpkin.
