Was it sagging much?

Lots of guide wires. Now that I'm looking at it, how did they get that elephant up on and down from those roofs?

But truly it's a boring game. I have a few dozen - geography, holiday, humor. And a few from dad who brought home anything he found. There are WWII postcards, from both sides. and a few cabinet cards, which are large, stiff cards, sometimes of famous people, or not.

Does get boring pricing them. Been just marking most for a dollar. First day I put in a shoe box full, sold almost a hundred of them.

I've had a oouple lots that cleared about a dollar per postcard, but then also a couple of $3 cards and a $10. You're right, obscure US geography and places is what sells. And so far mine have gone mostly to locals.

A few have gone for $30 and $40 and more in the $5 to $10 range. Small town RPC do great, just never know which ones.

I had a sale of 7 thin postcards, and one got damaged with a corner folder over. I have been using a quality #10 envelope with a glued on label. Buyers tells me I needed cardboard. Well you can't make it too stiff, they tell you that up front. Do you buy these yellow manilla 6x9" envelopes and put a cardboard frame around them? Thickness has to be uniform, and not stiff. Somedays the whole eBay is just too much for me.

and if it is 3 or more it cost more as it is not flexible enough to go thru mailing machine. Only 1 or 2 stamps do it. She bought these off of eBay. Will get a little smaller ones next time.
Problem with more than 3, you are talking almost $4 shipping. We've been putting single ones on with $1.99 with free shipping. The ones that get several bids pay for the rest.
Still figuring it out.

Will try some of the others
