The rarest Canon lens cup

Back when I was teaching English as a Foreign language in South Korea I was Really getting into photography and just To confuse The Living Daylights out of My young students I got one of these Canon lens cups to drink my tea from in The classroom which seemed to absolutely Amaze them almost as much as me putting Milk into my tea which was totally Unheard of for them although they're Still available today this particular Cup is my favorite and it's quite rare I Think it was taken off the shells for Looking a little too much like the Official Cannon LS without being Licensed unfortunately it developed a Crack and started leaking but I still Had fun using it in YouTube videos to Trick my viewers into thinking I was Abusing expensive camera lenses
