Retro Guestbook is an innovative message system that allows friends and family to leave audio messages at special events (indoors and outdoors) and even if they are unable to attend the event. Hear your loved ones' voices whenever you choose and treasure your memories for a lifetime. How it works: I set up a beautiful analog phone on a table or desk with a personalized sign instructing guests to pick up the phone receiver and a leave voice message. The messages are saved to a flash drive and ultimately to a cloud service, which I then email to the client via in a zip drive.
