John Casey has taken the humble rubber stamp to a whole new level. In today’s digital world, who would have thought that an extraordinarily friendly Irishman who began making rubber stamps back in the 1970s could still be in business today? The current iteration of the store offers more than a thousand novelty stamps mounted on maple molding. Plus, Mr. Casey can customize a stamp for just about any request, crafting it in his tiny shop in no time — all with a smile.
