Hiya Ginga! ^.^
I actually have two bank cels I aquired at roughly the same time, so I'll just go ahead and mention both. And yes, both still remain in my gallery even though they were purchased about 11 months after I started collecting.
One is the Rei S Movie Opening cel...that I aquired from Acetate Addiction. Since Rei reminds me so much of my sister, and I loved Rei in that cute detective outfit, I was very happy that AA took my offer so I could give her a good home. ^^ As I re-watched the SM series over again, Rei quickly grew into becoming my favorite senshi, along with Usagi. Their friendship that they have together signifies a strong bond, even though they may bicker often. This is one of my favorite cels b/c of her cute outfit and the look of surprise on her face. This one isn't going anywhere as it will stay with me throughout my collecting years.
The second bank cel that I aquired not too long after Rei was through Luna-art, a very well known Sailor Moon collector. She's such a sweetheart and after talking to her several times about a bank cel she went through her collection and found that she had a similar one in her possession and she was willing to sell it to me. Estatic, I jumped right in and thanked her up and down. This cel happens to be the R Opening of Sailor Moon spinning with clocks surrounding her. I don't know what my appeal is with the clocks, but I love how they twirl around her. As I have mentioned in some of my descriptions in my cels, I love not just full frontal shots, but perspective shots from the side and profile shots. Even though this shot may not be a frontal, the way the animators drew so much detail into Sailor Moon still reflects movement that could be considered realistic...and those shots mean more to me than just a regular close-up shot. I guess it's the artistic nature in me that relishes those shots... ^___^
Wow that was long, but I'm glad I was able to share! Can't wait to see your latest batch of goodies Ginga, I'm totally excited for you! ^_~
