The letter sheet is in good condition.  The flap is not sealed.  It has light pencil notations on the front and back and what appears to be very light hinge marks on the back.  Note that the vertical dark shading on the left side of the letter sheet is not on the sheet itself but is the result of the photographic process.

Note: On multiple purchases with shipping costs, I will use the item with the highest shipping cost and then charge $.20 for each additional item, up to a maximum of $3.50.  Any number of stationery items, with few exceptions can ship for $3.50.  If you do have multiple purchases, please wait for my invoice with the adjusted shipping cost.
