Maybe interesting toy in junk shop...

I was poking around a junk shop that I visit from time to time and I saw a toy. It didn't really strike me as that interesting when I saw it but I've been wondering about it since I left the place this morning. The thing was mostly red plastic with a cardboard bottom. It had a two-prong AC cord and a four prong "old fashioned" telephone jack. It had two big buttons and a spool of paper tape mounted on the front. The tape was about 1/4 inch wide. I call it a toy because it had that sort of feel about it. It was not clearly labeled as such. It was also styled in a way that suggested late 1960s to me. The whole thing was the size of a small shoe box. I can't find anything like it in google searches. I wonder if it might have some early modem like device in it. Does this description "ring a bell" with anyone?
