Currently on eBay is this vintage Maurice Utrillo print matching the well-known framed picture in the living room of the I Love Lucy set. This one for sale has some damage so read the sellers description for details. See it on eBay :
Next is a hard to find small Gouda ashtray that matched one used as a small wall plate in the I Love Lucy kitchen. There were a pair of these each side of three larger ones.
A similar small ashtray was later seen on a small side table next to an armchair to the left of the Hollywood apartment set.

Also on offer is a pair of owl bookends like the bookends I repainted to match the pair on I Love lucy in a previous project:
The above items are currently on eBay at the time of writing.
I also spotted this TV lamp with plume design similar to one seen on the I Love Lucy set 
It was recently sold on eBay however this was the first time I have seen one with a maker mark by Stewart B McCulloch who also made the pair of asian man and woman mantel statues
