If you have discovered this blog by finding a piece of artwork with a label on the back, that label should also have the name of the artwork, i.e. "postcard 25" or "weathergram 62" or "Tag 86".
The quickest way to find your item is using the "search" line at the top left of the screen with the orange "B" in front and the magnifying glass at the end- type in the item & number on the label and then click on the icon at the end..... it'll take you straight there! Post a comment to say you found it!
If you can't find it that way, leave a comment on the most recent post, and I'll cut and paste it to the correct place for you!
Next time I'm in, I'll find your comment and reclassify the lost item as found.
