Is it Pyrex?

I am not sure if this small white bowl is pyrex. It is the same size as my other small pyrex bowls. Has the same weight, has the look but has no writing anywhere on it. I also found a white fluted cake plate. I adore it and adored the $3 price tag. I did find a vintage sheet. I am not sure if its really vintage or reproduction vintage. Do you know? I saw one like it on Etsy and they say its vintage. But I am not sure. There is no tags on mine and usually I find the tags and that is how I know for sure its vintage or I know the pattern. But I have never seen this pattern.

I have been so ill for the last 2 days. I was not even able to go see my favorite singer Tori Amos. She was in town yesterday and I was puking for 2 days so I could not go. I bet she was awesome.
