Unfortunately, this exact one is no longer available, but I linked a similar one!
This backdrop was exactly what I was looking for! It is big, looks as advertised, and made with a material that is lightweight yet sturdy. It has been almost a year since we threw this party for our son and since both our sons are still OBSESSED with superheroes I have a feeling I will get to be using this backdrop for the next several birthdays!
For the sake of space, we propped the cake table in front of the photobooth backdrop. Since the party was during lunchtime, everyone ate right away, allowing us to do the cake cutting closer to the start of the party. Once we sang happy birthday, we then moved the table to open up the area for photos. We got the backdrop to stay up like this by using PVC pipes!
The link I provided for the capes and masks is not the exact one I purchased from however, the capes are the exact same and there are more options in this set. I was unable to provide the link I purchased from because that page no longer exists.
