There are different versions of the same cream.
Different formulas.
About 18 months ago I found out the chemist around the corner from the house sells Erasmic shaving cream for the princely sum of £1. I picked up a few tubes to see what it was like. The one I bought was the silver tube with black cap as shown in rhtoras' post. I was impressed by how easy it was to lather. The scent was fine, like a classic soap my Grandmother would have had in the bathroom.
