Norman Rockwell signed numbered lithograph

"The Bookseller" Circa 1975, number 163 of only 200 lithographs signed in pencil by Norman Rockwell..(RIP 1978)! Poshmark provides free authentication for items over $500 as stated below. shipping is also included free. It was wrapped up in bubble wrap and brown paper so it is In excellent condition. Matte-mounted in a very high class frame under plexiglass. I could only find two auctions of this lithograph series of 200 prints recorded on the internet: one in 2003 at $805 by Swan Auction Galleries, and one in 2014 at $1,266 by GOVDEAL; prices realized include buyer's premium and Hammer price. You can find that unscrupulous copiers of this series sell canvas-like copies or poster copies blocking out the numbers and sometimes the signature for 30 to 200 bucks on the internet. I am not one of those and this is not one of those copies. This is an original Norman Rockwell from a series that very rarely surfaces!
