Is there a way to restore a previous version of an online store page ?

[terryt]

Hi everyone - I did something really dumb today. I was working through Yoast, trying to improve my SEO. One of the steps asks to copy your store logo and paste it into a box. So, I opened my store, went to dashboard and the home page, where my logo shows up, and I believe I right clicked the logo and copied it. I closed off the home page, and when I opened it a little later, my banner was gone !!!!????
I am freaking out because I don't know how to fix it. Could anyone advise what to do next ?
