Comment: The items were reproduction and not true ephemera. Be careful because you would get a 3 rating for not meeting swap requirements. Maybe read up on ephemera to be ready for this type of swap in future.
Comment: Thank you for your first ATC ever! You asked for suggestions, atc's have a standard measurement of 2,5 by 3,5 inch, or 6,4 by 8,9 cm. Like a baseball card, yours was a little to big to fit in the pockets. And a thick kind of paper as a backing would be great. Like a postcard.
